How To Pleat Fabric? Part 1 – Permanent Accordion Pleats Home » Fabric Manipulation Techniques » How To Pleat Fabric? Part 1 – Permanent Accordion Pleats

After I have read PauI Jackson’s book about pleating, I felt really inspired to start hand pleating fabric. How to hand pleat fabric at home is touched on in the publication fairly briefly and the lack of detail has led me to trying out my own ideas and resulted in slightly refined methods compared with those described in Paul’s book.

In this tutorial, you will learn what tools you need and what steps are to be followed to hand pleat fabric permanently at home applying heat. You will create an accordion type of pleat using A4 kraft paper (see the images below). For big project apply the same technique with larger paper.

If you decide to pleat fabric and use it in your sewing projects, you might be also interested in my blog post about hemming pleated fabric.

Before you start, make sure your working area is clean and large enough, while all tools listed in this tutorial are at your fingertips. You need to be able to spread out the pleating moulds and keep them free from dirt, marks, or stains so that these can be reused in the future without any risk of blemishing your fabric. Be prepared that pleating takes some time and practice as you have to work precisely in order to get satisfying results. Let’s start with the necessary tools.

What tools you will need for hand pleating fabric?

For hand pleating with heat you will need the tools listed below:

If you would like to skip the description of individual tools, look here and read the instructions.

1. Kraft paper 200 gsm will be needed for pleating moulds

Do not buy paper with much less than 200 gsm, otherwise, the pleating process will misshape not only the paper but also the pleated material.

I recommend buying kraft paper in sheets for smaller experiments like this one. You can always get a big roll of paper for larger projects later on.

If you fail to buy brown kraft paper, bleached (white) paper can be used instead, it is a little more expensive option though. It too should have at least 200 gsm.

Do not use cardboard as it is ‘filled’ with air between the layers of paper. Apart from this, its paper plies are glued up in certain places. This prevents you from making a smooth and even mould (see the images below).

2. Long rulers

For smaller projects a ruler up to 50 cm (20 inch) long is sufficient. Later on, when you plan to pleat a full-length skirt, you will need a ruler up to 1 meter long (40 inch). (I use metal rulers with adjustable handles.)

3. Mechanical pencil

For drawing individual lines that will become accordion pleats at some point, you need a classic or mechanical pencil. I prefer using a pencil to a ballpoint pen or a sharpie. When you make a drawing mistake, the pencil marks can be erased easily.

A mechanical pencil is always sharp so that you can draw more precisely than with a classic one.

Whether you choose a classic or a mechanical pencil, make sure you are buying one with hard graphite that does not blur easily. 2H is a good choice.

In this tutorial, I use a 0.5mm filling size, but 0.3mm is fine too.

4. Quilting (omnigrid) ruler (optional)

The quilting ruler is useful when creating markings on the papers that will become your moulds (see further instructions).

5. Art knife

You do not need a super sharp art knife since the accordion pleats are going to be pre-pressed with its spine (not the blade).
Instead of an art knife, you can also use a ball pen that ran out of its filling, or another instrument that allows you to press thin lines into the kraft paper.

Always test the selected tool with your craft paper before pressing all your dawn lines.

6. Cutting mat

If you own a cutting mat, I recommend placing it underneath the paper before you start to press the pleats with an art knife or a similar tool. This keeps your table safe from damage. ( I also tried DTD or MDF boards instead, but they got bumpy and were no longer suitable).

7. Cotton twill tape

The twill tape will be used to tie up the pleating moulds with the fabric in between them. It is firm and flat and will not be damaged by the heat of the iron or the oven.

I do not recommend using round laces. During the pleating process they might misshape the moulds and thus the pleated fabric itself.

8. Iron or oven

Use an iron with steam to pleat with heat. It is suitable for bigger projects.

For smaller projects like the ones introduced in this tutorial, a conventional oven in your kitchen will do sufficiently. However, make sure it is clean inside. It must not leave any oil or other stains on your moulds and/or fabrics.

9. 100% polyester fabric

For this type of pleating, you will need fabric that is made of 100% polyester. While pleating with heat, the polyester fibres melt to some extent and bend in the shape of the moulds.

You can choose from 100% polyester satin, georgette, or chiffon, to name a few.

How to create moulds for hand pleating fabric?

I strongly recommend creating a small pleated sample like the one shown here every time you are about to use a piece of new fabric. Some fabrics are really tricky to fix in between the moulds, so it is extremely helpful to give your project a small-scale try before undertaking your intended big project.

1. Draw lines on A4 sheets

Repeat the following process twice that is with two A4 kraft paper sheets as you need both for pleating one piece of fabric.

Draw lines 1,5 cm (5/8 inch) apart from each other on the long side of the paper. A quilting (omnigrid) ruler is an ideal tool to do so. Place the ruler perpendicularly to the short side of the paper. On either side of the ruler create marks 1,5 cm (5/8 inch) apart from each other (see the image below).

Markings 1,5 cm apart from each other.

Work as accurately as possible. Make sure that the individual marks are exactly opposite to each other and connect them.

2. Press the drawn lines

The best method is to press the lines of the folds with the spine of an aft knife (not its sharp edge). You have to find optimal pressure. When you push the art knife too hard, you may unintentionally cut the paper and that is NOT what you want. When you push too little, you may not be able to fold the paper where it is supposed to be folded.

Try to work as precisely as possible, press the art knife exactly where you have drawn the lines.

Visible inaccuracies are not advised. If the pressed lines are not evenly spread, your moulds come out corrupt and will not fit together properly. As a result, pleating is hard and the result poor.

Press all the drawn lines on both sheets.

I have also tried other methods instead of pressing the lines with an art knife, but they did not work well. If you are curious about what does not work and why read the text below, otherwise, skip it and go directly to step 3.

DO NOT simply fold the paper

My first attempt was simply taking a sheet of paper and folding it. There are two problems linked with this approach. The first issue is that it is not easy to make the folds exactly where they should be, even with the outlines pre drawn on the paper.

The second issue was that the folds were too rounded as well as the fabric . The pleats on the material were neither appealing nor sharp.

DO NOT cut through the paper

I used the sharp side of the art knife and pre-cut some parts of the folds. I had seen some cut-through moulds somewhere on the internet and thought I should give it a try. The result were really sharp and nice pleats. Also the fabric samples came out really nice. However, the moulds were falling apart very easily after being used just once. It was impossible to re-use them.

3. Fold the pre-pressed lines

You begin by folding one half of the lines and then the second one. Put a ruler right next to the first line, slightly lift the kraft paper and push it against the ruler. Skip the second line and go to the third line. Repeat it- lift the paper on the left side slightly and push against the ruler. Do the same with the 5th, 7th lines and so on.

You will end up with a folded piece of paper like this:

Turn the paper to the other side. The pre-pressed lines are visible. Fold every second line and your mould is almost ready (see the images below).

4. Create the final shape of the accordion pleats mould

Gently push one end of the folded paper towards the other end and create an accordion. In this phase the folded lines gain the expected shape (see the images below).

Do not forget, that you need two moulds. In case you have created one only, make another one.

How to pleat fabric fabric at home?

1. Prepare the polyester fabric for the accordion pleats

Properly pretreat the fabric in the same way the final garment will to be treated. Wash or dry clean, let dry and iron. (In this tutorial, I’m using 100% polyester MICRO SATIN.) To read more about preparing fabric for your sewing projects, read this blog post.

Cut out a piece of fabric you would like to use for the accordion pleats. It should be slightly smaller than the unfolded pleating mould itself.

Also hem the fabric before pleating. Hemming a fabric that has already been pleated may result a visually unappealing design.

Hem the fabric before pleating. How to do so, please read this blog post .

2. Place the fabric in between the pleating moulds

Spread both moulds and carefully place the prepared piece of fabric on one of them. Align the edge of the fabric with the edge of the pleating mould.

Place the other mould on the fabric. Start at one end and push the ‘sandwich’ (two accordion moulds with fabric in between) towards the other end.

You should end up with something like this (see the image below). This is a tricky, but an important part of hand pleating fabric.

3. Wrap the moulds

Now take the cotton twill tape and firmly wrap it around the accordion. Go from one end to the other one and back. Place the node at the side of the accordion (see the images below). If your tape is too long, just roll up the redundant piece and place it beside the mould.

4. Pleat with heat (choose Method 1 or Method 2)

There are two ways to pleat with heat. For small projects use your conventional kitchen oven. For large ones using an iron is preferable.

Pleating method 1: Steam with iron

Set the temperature on your iron to the maximum degree and set the steam control to minimum. Hover the iron above the moulds for at least 5 minutes from one side, and 5 minutes from the other side. With the steam control on, do not touch the mould.

Do not steam too close to the moulds. Otherwise, the kraft paper absorbs too much moisture, gets wavy and the fabric inside will copy this deformed shape (see the image below).

Pleating method 2: Use your kitchen oven

In the first place, your oven has to be suitable for the size of your moulds. For the accordion pleats made from the A4 craft paper should definitely be sufficient. Select a program that does not use the fan at the back of the oven.

Place the prepared ‘sandwich’ on a grid in the oven. Place a tray with water under the grid. Set the oven temperature to 170 degrees Celsius (338 degrees Fahrenheit) and ‘bake’ for 20 minutes.

Observe the oven and moulds while baking the accordion pleats. DO NOT LEAVE THE OVEN UNATTENDED!
When the time is out, take out of the moulds. Use a pot-holder to protect your hands, the moulds are really hot!

5. Let everything cool down

After you have done ironing or finished baking your accordion pleats, let the moulds with the fabric inside cool down. The longer you wait, the better. After a while the moulds might seem cold enough, yet, inside there is still a lot of folded fabric which needs to cool down properly as well.

If you take out the fabric when it is still warm, the polyester fibres might get distorted and the pleated fabric will be not nice.

6. Take out the pleated fabric

After everything has cooled down, you can finally take out the fabric. Untie the cotton twill tape and spread the moulds a little. Lift the upper mould and take out the fabric. Now accordion pleats are ready and can be further used for your project.

Conclusion: How To Pleat Fabric? Part 1 – Permanent Accordion Pleats

I hope you enjoyed this tutorial. If pleating impressed you, I strongly recommend buying Paul Jackon’s book about pleating. You will find out how to add more interest to one type of pleat (see the images below). How to make other fascinating types of pleats and how to combine them together in order to create really attractive designs. In the first place, however, you will be able to construct your own pleating patterns.

If you liked this tutorial, you might also be interested in another type of hand pleating fabric – knife pleats.

    1. Hi Mona, thank you for your interest :). The technique would be the very same. For a large piece of fabric that you are planning to peat, use 2 large sheets of paper that can accommodate that piece of fabric.

      For example, if you want to pleat fabric that is 1m wide and 1m long (40” wide and 40” long), use 2 sheets of paper that are about 1,3 m wide and 1,2 m long (52” wide and 48” long) each. There will be some extra paper around the fabric. However in my opinion more is better than less. On the width, there is more paper as the fabric slightly ‘moves’ towards the other end of the moulds while folding the whole ‘sandwich’.

      Once you have two sheets of paper that are large enough, draw the pairs of markings, connect the markings, pre-press the drawn lines, and fold the paper. Then place the fabric in between your large moulds, fold the whole thing and tie it with the cotton twill tape.

      You will probably have to use iron and steam as a kitchen oven is quite small.

  1. This is fantastic ! thank you so much for the information given. I have one question: Do you know how much is 200 gsm in LB? where did you find that paper. I’m trying to find a larger roll because of the piece of fabric I need to pleat is bigger than the sheets you showed in this tutorial but i cannot find anything in gsm. Thank you!

    1. Hi, thank you for your comment :). To answer your questions:
      1) 200 grams/square meter = 0,44 pounds/square meter. If you type directly into google search “grams to pounds” a unit converter will show up. You can use it to convert meters to feet, grams to pounds, etc.

      2) I bought the roll in an online stationery shop. You can look among some stationery shops or try Amazon. It is also possible to buy a roll that is a little below 200 gsm (like 170 gms, but not less!). The paper has to be able to hold the accordion shape and the fabric. You can also contact some shops via email and ask for a suitable paper roll.

      If you have never pleated fabric, start making a sample accordion pleat like in this tutorial. Some fabrics are tricky to work with. I have to admit it is not as easy as it seems. I used my pleats for sleeve cuffs or other decorations of a garment.

      After you have done your sample (or not 🙂 and feel like doing a big project straight away, look at this video and see what it takes to pleat a big piece of fabric (I think I should include it in the tutorial :):

  2. Hi there,

    I am looking for someone to alter a dress made of micro-accordian pleated fabric. Any recommendations?

    1. Hi Mary,

      I don’t know what country you’re from. So I cannot really give you a recommendation. However, I would try looking for a local seamstress. She/he should be able to help you or might suggest someone else to help you with necessary alternations.

      Have a nice day 🙂
