Maple leaf for cutting A4 format. maple leaf stencil

Leaves are popular elements of various. Cutting templates allow you to quickly make a large number of identical parts that will realistically repeat the outlines of real leaves.

The cutout template is useful for both children's crafts and adult creative work.

Leaf stencils can be used by children in the following activities:

  • formation and consolidation of cutting skills;
  • development of the ability to work with a pencil and paint silhouettes;
  • production of applications in various techniques;
  • performing large-scale crafts.

Adult craftsmen can use ready-made templates in the manufacture of various creative crafts:

  • postcards;
  • photo frames;
  • items for interior decoration;
  • flat and voluminous compositions for photo zones and themed holidays;
  • bijouterie;
  • fabric applications for decorating textiles;
  • airbrushing.

Leaves cut according to the template can be used in various creative works that the imagination will tell the masters. To do this, you need to prepare the necessary template and select the appropriate materials for the idea.

How to get a template

You can draw a leaf template for cutting out with your own hands, but in some types of leaves it is quite difficult to reproduce small details.

There are several ways to obtain an accurate leaf silhouette:

  • One of the easiest and most fun ways is to trace the outline of a real sheet. To do this, during a walk, you need to collect a collection of leaves of various types and shapes.

Then they need to be straightened and dried. To do this, the typed material can be placed for a day between the pages of a thick book. The dried leaves are laid out on a white sheet of paper and carefully outlined along the contour with a soft, simple pencil.


A template for a paper cut sheet can be obtained by tracing a real sheet on paper

After removing the sample, all the lines are traced again to get a clearer shape. From the resulting image, you can make a template or stencil.

  • If it is not possible to collect leaves on a walk, you can use ready-made leaf templates. This method is suitable for people who do not have access to printing technology.

To get the template, you will need a sheet of white office paper and a very soft pencil. The image of the sheet must be displayed on the screen of a computer or tablet, setting the appropriate size. The paper is applied to the monitor, and the image is transferred to the sheet.


You can translate the flower template through glass, for example, on a window

Important! When tracing the outline, it must be remembered that if you press the pencil hard, the screen structure may be damaged. Therefore, the drawing is done with a light sketch, which is given a clearer outline on a hard surface.

  • A leaflet template that can be immediately used for cutting is downloaded and printed on a printer. At the same time, there are several options for working with electronic blanks.

The contours printed on a white sheet are painted with paints and cut out with scissors. Leaflets can be colored before printing, using a special computer program. You can also print color templates, supplementing them with small details using felt-tip pens.

Leaf templates can be printed on a printer

Needlework lovers can choose from a variety of options for making templates suitable for work.

How to make strong templates

The cutout template may need to be used several times. In order for such a blank to retain its shape for a long time, it should be made of durable material.

As with simple paper stencils, various methods are used to create durable templates:

  • The easiest way to make a durable template is to use a plastic corner folder to make it. Paper with images of leaves is placed in a folder, and the outlines are transferred to plastic using a marker.

The plastic sheet is laid out on a solid base (for example, a wooden board) and templates are cut out with a clerical knife. In this technique, you can create not only templates, but also stencils for working with paint. They are easy to clean and adhere tightly to the work surface.


The most durable template for paper cutting - a plastic corner folder
  • To make a regular paper template more durable, you will need a special laminating film and a regular household iron. The device is set to the minimum heating level.

A paper sheet is placed between the layers of the film and carefully drawn over the workpiece with an iron. The resulting part is cooled and excess material is cut off, retreating from the edge of 3-5 mm.

  • Durable templates are made of cardboard and transparent adhesive tape. Paper templates are traced on thick paper or cardboard and cut out. Each side is pasted over with adhesive tape, tightly connecting the sides. Excess material is cut off, retreating from the base 1 mm.
  • The fabric cutout template must be both strong and flexible at the same time. A part with these properties can be created from greenhouse film or textbook covers.

The easiest way to transfer an image of a sheet onto a film is to overlay it on a monitor screen. With the help of felt-tip pens, the leaf is circled and cut out along the resulting line. Such a template is easily fixed on the fabric with pins and retains its shape for a long time.


Another durable and strong material for making templates is X-ray.

Also, very strong templates are obtained from old x-rays. The process of making them is similar to working with plastic folders.

What can you do with stencils

Leaf-shaped stencils are used in interior decoration and furniture, clothing, and confectionery.

Stencils in the interior

There are many ways to use leaf stencils in the interior.

They can be used to create panels, decorate walls and furniture:

  • The autumn tree is made in the form of a small panel or a stationary wall image. On a white leveled surface, a large stencil is fixed in the form of a trunk with branches bent under a gust of wind. Such a stencil can be made from a film for greenhouses with your own hands.

Using leaf patterns, you can also decorate the wall of the room with a spring tree

After the base has completely dried, stencils of maple leaves are randomly placed on the branches. With the help of a sponge, the silhouettes are filled with red, yellow and orange paint. If desired, fine details can be drawn with a thin brush.

  • A composite panel of fern leaves is made from thick sheets of paper or white cardboard placed in wooden frames, on which fern leaves of various configurations are applied using a stencil. A plastic stencil is superimposed on a white sheet and secured with paper clips.

Using a sponge or brush with a hard bristle, the image is filled with green paint. The drawing is dried, covered with a laminating film and inserted into a frame. A panel consisting of 5-7 pictures hung in random order looks beautiful.

  • Usually, glass and mirrors in the house are decorated with snowflakes for the New Year holidays, but with the help of stencils in the form of leaves, you can create unusual autumn compositions. For their implementation, you will need moisture-resistant stencils, multi-colored gouache and a large hard brush. With the help of these materials, you can depict leaf fall on the window and make a beautiful multi-colored frame on the mirror.

Clothing design

Unique clothes with an interesting pattern make their wearer stand out. It is very easy to make such a thing at home using a stencil.

To do this, you will need the following materials and tools:

  • leaf stencil with small details;
  • plain T-shirt (or other item of clothing);
  • acrylic paint for fabric;
  • brush;
  • white paper or cotton cloth;
  • plastic sheet;
  • iron.

The stencil can be made from a film and pinned to the base with pins. But it's easier to print it on self-adhesive paper and stick it to the fabric.

Bag decor with autumn leaves

Having prepared everything you need, proceed to the following steps:

  1. Smooth out the fabric and lay it out on a flat surface. Place a sheet of plastic under the working side, the size of which corresponds to the selected pattern.
  2. Using a brush, the pattern is carefully transferred to the fabric. The intensity of the color depends on the quality of the paint and the number of layers applied.
  3. The finished drawing is left to dry, which lasts 20-24 hours.
  4. The dried drawing is covered with a sheet of white paper or cloth and fixed with an iron.

Confectionery

Plant stencils are a popular tool for decorating confectionery and drinks.

Confectionery templates are made from plastic or silicone sheets. At home, you can create from plastic folders. The sketch of the stencil is first drawn on paper, and then transferred to plastic and cut out with a clerical knife.

Templates for crafts to school

Cutout templates are often used in creative activities in kindergarten and elementary school. The choice of a suitable template depends on the age of the children and the complexity of the craft.

A tree with bare branches is drawn on cardboard. Then the figure is cut out, forming a rounded crown. The entire surface of the workpiece is covered with a transparent adhesive tape. At this stage of the work, children can take part in coloring the tree.

Each child will need 2 veined maple leaf templates. Children cut and color the leaves themselves in bright autumn colors. After the paint has dried, a small piece of double-sided tape is glued to the back of the leaves and placed on the branches of the base.

The tree is a universal educational aid, which is filled with various removable elements. Their choice depends on the time of year and the topic of the lesson.

  • Without unfolding the paper, cut out 2 identical parts in the form of a leaflet.
  • Small details are drawn on the workpiece with a felt-tip pen of a suitable color.
  • One of the paired leaves is attached to the branch with a small piece of paper tape.

  • The second part is covered with glue and connected to the element fixed on the branch.
  • For a branch to look spectacular, at least 12-15 leaves are needed, so work with preschool children should be carried out in groups.
  • Fully decorated branches are dried in an upright position, set in a vase.

Felt wreath

The pattern of the leaflet for cutting is used not only when working with paper, but also for making fabric crafts.

To create a felt wreath, you will need the following materials:

And although autumn is already running out, and everyone is looking for it with might and main, the theme of autumn leaves is popular at all times.

The needleworkers especially liked the maple leaf, the template of which I present to you today in different variations. It is so unusual, beautiful, and the color of this leaf is very different - yellow, orange, red, not to mention green.

In general, it is not surprising, but a maple leaf stencil can be found quickly and easily.

Where? In nature itself, of course! We go to the nearest park for shopping, collect fallen leaves - and voila! - a sketch according to which we will draw in our hands.

There is nothing easier to attach a leaf (after straightening it, of course) to the paper and carefully circle it. The “web” of lines can then be drawn on your own. Or you can use contour- to get an unusual effect.

But not in all regions of Russia, unfortunately, this tree grows - this is the time. Someone did not have time to make a herbarium for the summer-autumn, and in winter it is already impossible - these are two. Well, it’s so simple, without leaving your home, print a picture and start creating, right?

Here is a coloring template with small leaves. Suitable for coloring with pencils.

STRIPED COLORING.

The coloring of silhouettes using the CONTRAST STRIP method looks very nice. That is, we take the usual coloring with leaf patterns and draw straight lines over the picture under the ruler. And then we color all the objects on the sheet, alternating these linear zones in color.

In the example below, we see that the coloring is drawn using a compass (round lines) - but this is not necessarily your lines can be made to fit a straight school ruler.

Here are suitable leaf patterns that you can draw in stripes (straight or arc stripes) and then color in the same style. Alternating pencils from stripe to stripe and using different colors for the background areas and different colors for the leaf areas.


Leaf patterns

for SECTOR COLORING.

Very beautiful crafts on the theme of autumn will turn out if the autumn leaf template is divided into sectors and each sector is painted separately with close shades of the palette or vice versa with contrasting colors.

It turns out the feeling of STAINED GLASS ... as if the picture is made up of multi-colored glass. But in fact, this is an ordinary watercolor, or crayons, or a pencil (your choice).

As you can see, everything is simple. We take a sheet template - we divide it into sectors. each sector is painted over with its own color (it is possible with smooth transitions with spills of shades from one to another) And then we circle the entire contour of the sheet along the edges with a clear color.

To facilitate your work, I give TEMPLATES of leaves with ALREADY READY sector sawing.

You can simply print out these pictures and hand them out to the children and offer to color each sector with crayons of a different color. To make coloring faster, you do not need to change the crayon in your hand every time you move to a new sector. Show the children that it will be faster if you first take a red crayon and color them in 5-7 different sectors (not neighboring ones, but randomly). Then take a yellow chalk and also randomly fill in 5-7 other sectors. It will be faster, and you will meet the time frame of the activity class.

Large leaf patterns can be filled with a thin brush with watercolor or gouache (such as the stencil below).

Olga Klishevskaya, specially for the site

The article presents a variety of paper accordion leaves, templates and step-by-step instructions for creating a particular sheet. Such leaves can be in very different colors, for example, if they are timed to coincide with autumn events - it is better to use colored paper in yellow, orange and red colors, for spring - leaves of light green and green shades would be a good option. Even for winter celebrations, you can make leaves from silver or white paper.

For work you will need the following materials:

  • Colored paper of a variety of colors suitable for leaves;
  • Scissors, glue stick, simple pencil.

Paper accordion leaves step by step: 8 options with templates

1 option. Maple leaf paper accordion

You will need yellow or green colored paper. Cut off an arbitrary rectangle from it.

Fold it in half.

Redraw or print your template. Cut it out and attach it to the colored paper folded in half, keeping in mind that the straight long side on the template falls into the fold.

Circle with a pencil. The fold is on the left in the photo. And in the future, all the stages presented with paper folded in half will be with a fold on the left.

Cut out the blank, carefully cutting off all the wavy lines.

Now open it. You should get a similar detail, with symmetrical extreme sides.

At this stage, it's time to make a paper accordion. It is better to start from the bottom, widest side. Bend a small fold, no more than 7 mm wide, but extending over the entire area of ​​\u200b\u200bthe sheet. Carefully press, and then bend the same fold in the other direction. Repeat this process until all the paper has turned into an accordion.

For convenience, turn the harmonica with the long side up.

Find the middle and fold in half. Press well, especially around the bottom fold, and glue the inner sides together. In the photo, this area is shown by arrows.

Depending on the structure of the paper, sometimes it becomes necessary to glue two or three lower folds of the sheet. Most often they diverge in very thin paper. Dense keeps well all the folds together and without glue.

The accordion paper maple leaf is ready, straighten its folds and glue a thin stem.

Option 2. Autumn sheet of paper accordion

Of course, it can be not only autumn. If you make it from green paper, the leaf will be quite spring or summer.

To create it, you also need a piece of rectangular paper.

As in the first option, the paper needs to be folded in half.

Then you should use a template or draw a simple zigzag line that resembles one part of a Christmas tree.

This line should start from the fold of the paper and end at the bottom of it.

Cut out the pattern obtained using a template or your own efforts.

Open up the sides.

Make small folds, length from one side to the other, and 5-7 mm wide. If the sheet is large or the children are small, the folds may be larger.

The accordion is made, for convenience, turn it over with the wide side up.

Mark the middle and carefully fold in half. Press down, especially at the very bottom.

Apply glue to one of the inner sides and glue them together. In the photo, this area is shown by arrows. If necessary, glue a few folds at the very bottom of the leaf.

In the end, straighten the sheet with an accordion a little and glue the petiole, which is a thin strip of colored paper from which the sheet itself is made. But such a stem is not strong, it can only complement the leaf, and, for example, gluing leaves to a homemade tree will not work. It is better to use colored cardboard for these purposes, or colored paper twisted into a flagellum and threaded through a hole in the bottom of the sheet.

3 option. Oak leaf from paper accordion

The outline of this leaf is similar to an oak one, only the longitudinal folds impair this definition a little. But as a variety, this version of the sheet is also useful, especially in those works or events where you need a lot of leaves of various shapes.

Cut out a square from paper.

Fold it in half, the fold is on the left.

Use a template or draw large waves yourself, starting from the side of the fold and reaching to the bottom side.

Cut the part through two sides at once, but without touching the left. She must be whole.

Open the paper.

And, as always, make thin folds starting from the widest part of the paper. Gently fold all the paper into an accordion, one fold in one direction, the next in the other. For convenience, the paper can be turned over during operation. In extreme cases, draw light longitudinal lines with a simple pencil and fold the leaf along them.

Place the resulting harmonica with the longest side up.

Find the middle and fold the accordion in half. Glue the inside sides.

Straighten the folds, glue the petiole and the accordion oak leaf is ready.

4 paper accordion sheet option

This species is similar to a hornbeam or beech leaf. Yes, and on the leaves of many other trees. The main thing is that no templates are needed for it, it is extremely simple to make it.

To make this oblong leaf, you need triangular paper. You can first cut a square out of paper.

Fold in half, joining opposite corners.

Cut in half and you get two triangles.

One sheet will need one triangle. Turn it wide side down and start making folds there, like an accordion.

Turn the whole triangle into an accordion.

For convenience, turn it over with the longest side up.

Find the middle and fold exactly in half, connecting the tips. In the middle, apply glue to one of the sides and glue the side parts together.

Spread a little and glue the stem. The sheet is ready.

5 paper accordion sheet option

The most common type, the shape resembles the leaves of poplar, linden, birch. For a change, let it be green, although the leaf is no less interesting in the autumn, yellow-orange version.

It needs a not very wide paper rectangle.

Fold the rectangle in half, the fold in the photo on the left.

Use a template or draw yourself a convex line, the beginning of which is from the side of the fold, and the sloping slope reaches the bottom side of the sheet folded in half.

There are no exact proportions and markings. If you need a more prominent narrow tip, the indentation on the line can be made more pronounced.

Cut out the pattern without touching the left side.

Open the paper.

Make an accordion, starting with a straight, longest side. As usual, the width of the folds is ideal in the region of 5-7 mm.

Flip the accordion straight side up.

Fold in half and glue the insides. If necessary, glue the bottom folds.

Straighten the leaf and glue the stem.

6 option. Another maple leaf made of accordion paper

There are quite a few varieties of maple leaves made from paper folded into an accordion. It all depends on the template. There are very simple ones, which can be drawn almost arbitrarily, and more complex patterns, which it is still desirable to follow as accurately as possible. In the second case, maple leaves are more perfect, close to the original.

Despite the fact that the very first I already showed one type of maple leaf, I still can’t resist and show another one that I really liked.

For it you will need square-shaped colored paper.

This square then needs to be folded in half.

Print the template and carefully reproduce its lines on colored paper, considering that the fold is on the left.

Then everything is as usual. Open paper detail.

Make narrow folds, starting from the straight, wide side of it and all the way to the top.

Find the middle and fold the accordion-folded paper in half. Here you can see that this yellow paper is thinner than the previous ones, at the very bottom the folds are not held together. Therefore, they need to be forced to do this with glue. You can safely apply glue at the fold on the three lower folds. And, of course, glue the inner two sides, where shown by the arrows.

Straighten the folds a little, glue the stalk and a beautiful, in this version, autumn maple leaf is ready with an accordion.

7 variant accordion leaves

A simple round leaf. It can be a variety of colors inherent in the leaves.

You will need a rectangular piece.

Fold it in half.

Using a compass or something suitable round, draw a rounded line connecting the sides of the paper. Fold in the photo on the left.

Cut along the contour.

Open, and you get an even semicircle.

Make small folds, starting from the straight side of the semicircle and up to the very top.

Turn the accordion piece over with the long, straight side up.

Fold in half and glue the insides.

Gently straighten and glue the stem. The round sheet is ready.

8 option. Thin oblong accordion leaves

The form is inherent in the leaves of willow, olive and some others.

To make such a sheet, you need a rectangular, rather narrow strip of paper. The narrower it is, the thinner the leaf, although it is more difficult to make very thin.

Fold the strip in half.

Draw a slanting line. Please note that in the photo the fold of the paper is on the left.

Cut along the line and you get a double triangle.

Explore its parts.

Fold into a small fold. As you can see, it is problematic to make even folds on very narrow paper, but this will not be displayed on the sheet.

Turn the long side up and fold the harmonica in half. Glue the center.

It will turn out such a narrow sheet of paper accordion.
