What is a Fabric Stiffener?

Fabric stiffener is a special product that adds stiffness to fabric. It helps the fabric hold its shape and stay firm. You can find many types of fabric stiffeners in stores, like Mod Podge Stiffy or Aleene’s Fabric Stiffener.

But it’s also fun to make your own DIY fabric stiffener at home with simple things like cornstarch or PVA glue. The homemade versions work well for lots of projects and can save you money.

Why does Fabric Need to Stiffen?

Knowing about fabric stiffeners leads to an understanding of their importance in crafting and sewing. Sometimes, a garment or craft project needs some extra body or support. Stiffening the fabric can give it the necessary structure.

For example, collars and cuffs on shirts look better when they’re crisp and hold their shape. Also, if someone is making things like fabric baskets or certain types of costumes, those items need to be sturdy enough to stand up on their own.

Adding stiffness to fabric also makes it easier to work with. Cutting and sewing become simpler because the material doesn’t slip around as much. When artists create with fabrics, such as in quilts or wall hangings, they often want parts of their design to pop out more.

Making these pieces stiff can help achieve this effect beautifully, giving life and dimensionality to the artwork.

How to Stiffen Fabric: Sewing Methods

For sewing enthusiasts seeking durability and structure, knowing how to stiffen fabric permanently is a game-changer. Continue reading for innovative home solutions and commercial options to achieve the perfect rigidity.


Use a fusible interfacing

Interfacing is a great way to stiffen fabric, especially when making clothes. It’s like a secret helper that sits between layers of fabric and adds stability without being seen.

You can find interfacing in different weights to match the kind of fabric you’re working with. To use it, cut the interfacing to the shape you want. Place it onto your fabric piece, and then iron them together.

The heat from the iron activates the glue on one side of the interfacing, which sticks firmly to your fabric, giving it strength.

There are two types: fusible and sew-in. Fusible is popular because you only need an iron to make it stick. Sew-in needs you to sew it into place for those more delicate fabrics or if you don’t want any extra stiffness from glue.

Whatever your purpose, interfacing gives projects long-lasting form and structure.


sewing boning

Beyond using interfacing, boning offers another method to give fabric shape and stability. It involves inserting thin strips of plastic or metal into channels sewn onto the fabric.

These strips help the material hold a certain form, which is ideal for garments like corsets or structured dresses. Sewers often choose to bone when they need parts of their clothing to stand out or stay up without folding over.

Boning works well with heavier fabrics that need extra support. For example, if someone wants to make a dress with a full skirt that doesn’t collapse, adding boning can create that effect.

This technique needs sewing skills. You must attach the boning accurately for it to work right. But once in place, it provides long-lasting stiffness and shape for any project.

How to Stiffen Fabric: Use DIY Fabric Stiffeners

With a mix of household items and a touch of creativity, DIY fabric stiffeners offer an affordable and customizable way to give your textiles rigidity. Discover how you can craft these solutions yourself in the sections below.

Mix Cornstarch with Water

Cornstarch is a great way to stiffen fabric at home. Mix it with water until it’s smooth. Then, heat it in a pot until it gets thick. Spread this paste on your fabric and let it dry.

The fabric becomes harder and keeps its shape well after this treatment.

Next up is Elmer’s glue, another item you might find around the house.

Use Elmer’s Glue

Elmer’s glue offers a simple way to harden fabric. Mix equal parts glue and water in a bowl for an easy homemade stiffener. Soak the piece of fabric in the mixture, ensuring it gets fully wet.

After that, squeeze out excess liquid, but be gentle so you don’t twist the fabric out of shape. Lay the treated material flat or mold it as desired, and let it dry until completely hard.

People often use Elmer’s glue because it’s safe and washable before drying. It works well for projects where you want to stiffen fabric for sewing or crafting, like making fabric bowls or giving stability to collars and costume pieces.

Once dry, this method provides permanent stiffness unless the material gets wet again.

Mix Flour Starch with Water

Flour starch is a classic way to stiffen fabric. To make it, mix one tablespoon of starch with two cups of water in a pot and cook until it thickens. Cool the mixture before using it on your fabric.

Lay the fabric flat and brush the flour paste over its surface evenly. Once dry, you’ll notice your material has become firmer than before.

For extra stiffness, apply another layer after the first one dries completely. This method allows you to shape your garment or craft into its desired form while giving stability to the fabric.

Remember not to wash treated items; this will soften them again.

Use Rice Starch

Much like flour starch, rice starch also serves as a great way to stiffen fabric. To make it at home, you need only two ingredients: uncooked rice and water.

First, wash the rice to get rid of any dirt or oils. Then, let the clean rice soak in water for about 30 minutes. After that, strain the mixture and keep the milky liquid—that’s your homemade rice starch! It is perfect for giving your fabric a smooth finish and durable stiffness.

To use this method, dip the fabric into the liquid and squeeze out any excess. Spread the material out flat to dry; no ironing is needed here! As it dries, you’ll notice how much stiffer your piece becomes. This method is ideal for projects that require firmness without adding weight or thickness to the material.

Apply Gelatin

Gelatin is a handy option for stiffening fabric at home. It’s clear, and it adds strength without changing the color or texture of the material. People mix gelatin with water, soak their fabric in it, then squeeze out the extra liquid and let it dry into shape.

This method works well for crafts where you need the fabric hard, like for bows or costumes.

To use gelatin, boil water and sprinkle in powdered gelatin. Stir until it dissolves completely. Dip your fabric into this solution. Coat it evenly. Then, get rid of any drips by squeezing gently.

Spread your project flat or mold it to how you want it to stay. Once it’s dry, the item will hold its form nicely, thanks to the gelatin’s stiffening powers.

Mix Sugar and Water

Sugar is not just for sweetening your tea. It can also make the fabric stiff. Mix sugar and water together until the sugar dissolves, then soak the fabric in this sugary solution. Once soaked, shape the fabric as you want and leave it to dry.

As it dries, the sugar forms a hard layer that keeps the fabric stiff. This method works well for projects where you need to stiffen the fabric temporarily. Because when you wash it, the stiffness goes away.

For those who craft with delicate materials like lace or thin cotton, using sugar is an easy way to get that crisp look without spending much money. Just be careful; if you use too much sugar or don’t dissolve it properly, your fabric might become sticky or attract insects! Always let your sweetened material fully dry in a warm spot away from bugs and dust.

Spray Hairspray

Moving from kitchen staples to something found in the bathroom, hairspray can also make fabric stiff. People often use it to keep their hair in place, but it works on cloth too. Just spray the hairspray evenly over the fabric from a distance until it covers all of it.

Let the material dry, and you will have a stiffer fabric that keeps its shape well. Hairspray is good for small projects because you can control how much stiffness you want by how much spray you use.

It’s quick and dries clear, so your project looks neat when done!

Use Wallpaper Paste

Wallpaper paste is not only for hanging paper on walls. It’s a great way to make the fabric stiff, too. You can find it at most stores or make it at home with flour and water.

To use wallpaper paste as a fabric stiffenermix it up according to the package directions. Then, brush the paste onto your fabricspread it evenly, and let it dry completely.

The stiffness of the fabric will vary based on how much paste you apply. For heavier fabrics or projects that need extra strength, add more layers of wallpaper paste once each layer dries.

This method lets you shape the fabric into forms and keeps them firm after drying. Just remember to work in a well-ventilated area because some pastes might have strong smells.

How to Stiffen Fabric: Use Commercial Fabric Stiffeners

While DIY concoctions offer creative control, commercial fabric stiffeners provide convenience and professional-grade results. They ensure that there’s a perfect solution out there for every project.

ModPodge Stiffy

ModPodge Stiffy is a popular choice for making fabric stiff. It is a strong liquid that comes in a bottle. You brush it onto your fabric, let it dry, and the material becomes hard.

Comparisons: DIY vs. Commercial Stiffeners

When it comes to stiffening fabrics, crafters and sewists often debate the merits of DIY concoctions versus commercial stiffeners. Each type has its pros and cons, which can affect the outcome of a project. Below is a comparison outlined in a table, detailing the effectiveness of homemade and store-bought fabric stiffeners.

Stiffener TypeProsConsBest Used For
DIY Stiffeners (e.g., Cornstarch, Glue)Economical Readily available ingredients Eco-friendly optionsMay be less durable Can attract pests Inconsistent resultsTemporary projects, Lightweight fabrics
Commercial Stiffeners (e.g., ModPodge Stiffy)Long-lasting stiffness Professional finish Precise applicationMore expensive Chemical smell May require ventilationHeavy fabrics, Permanent installations

Homemade stiffeners can be a quick fix for lightweight fabrics, but they often lack the staying power of their commercial counterparts. Commercial products deliver a reliable hold, though they come with a higher price tag and the potential for fumes. The choice between DIY and commercial fabric stiffeners will depend on the fabric, the project’s requirements, and personal preferences.


Stiffening fabric at home is easy and cost-effective. People use common items like cornstarch or glue to get the job done. For tougher jobs, commercial stiffeners are available, too.

Each method has benefits, depending on the project’s needs. With these tips, anyone can make fabric as stiff as they need it to be.
