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 a DIY fabric stiffener at home with simple ingredients like cornstarch or PVA glue. Homemade versions work well for many projects and can save you money.

Why Does Fabric Need to Stiffen?

Knowing about fabric stiffeners leads to understanding 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. Stiffness can give fabric a high-quality, durable feel that will make a dress (like this lovely babydoll dress, for example) feel more luxurious. Also, if someone is making things like fabric baskets or certain types of costumes, those items need to be sturdy enough to stand up independently.

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: 2 Sewing Methods

Knowing how to permanently stiffen fabric is a game-changer for sewing enthusiasts seeking durability and structure. Continue reading for two sewing options to achieve the perfect rigidity.

1. Interfacing

 

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

Interfacing comes 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 it together.

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

The other interfacing 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.

2. Boning

Beyond 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, 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: 8 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!

3. 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.

After this treatment, the fabric becomes harder and keeps its shape well. Once you finish your project, washing it will remove the cornstarch, restoring the original softness.

This method suits natural fabrics more but may not work well with synthetic materials.

4. 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 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.

The glue mixture will provide a temporary stiffness, but it can be washed out with water.

5. Mix Flour Starch with Water

Flour starch is a classic way to stiffen fabric. 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 evenly over its surface. Once dry, your material will become firmer.

This method creates a temporary stiffening effect that can be washed out with water.

6. Use Rice Starch

Much like flour starch, rice starch is a great temporary way to stiffen fabric. You need only two ingredients: uncooked rice and water.

First, wash the rice to remove 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!

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.

7. Apply Gelatin

Gelatin is a handy temporary option for stiffening fabric. It's clear, and it adds strength without changing the material's color or texture.

To use gelatin, boil water and sprinkle powdered gelatin on it. Stir until it dissolves completely. Dip your fabric into this solution, coating it evenly. Then, squeeze gently to get rid of any drips.

Spread your project flat or mold it to your desired shape. Once it’s dry, the gelatin’s stiffening powers will help it hold its form.

8. Mix Sugar and Water 

Sugar is not just for sweetening your tea. It can also stiffen the fabric. Mix sugar and water 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 stiffens the fabric. 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, 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!

9. Spray Hairspray 

From kitchen staples to something found in the bathroom, hairspray can also stiffen fabric temporarily. 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!

10. Use Wallpaper Paste

Wallpaper paste is not only for hanging paper on walls. It's also a great temporary way to stiffen fabric.

Mix wallpaper paste according to the package directions to stiffen the fabric. Then, brush the paste onto your fabric, spread it evenly, and let it dry completely.

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

How to Stiffen Fabric: 3 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.

11. ModPodge Stiffy

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

Crafters often use Mod Podge Stiffy because it's easy to work with and dries clear. But this is not a permanent method.

12. Aleene's Fabric Stiffener and Draping Liquid

Aleene's Fabric Stiffener and Draping Liquid works well with various materials temporarily. Once you apply it, let the fabric dry.

The result is a hard finish that holds the shape you desire. It dries clear, so your design shines through. If you work on delicate pieces or intricate draping, this stiffener helps maintain every detail perfectly in place.

13. Plaid Stiffy

Plaid Stiffy is a ready-made solution that quickly turns your fabrics into hard, moldable shapes. People use Plaid Stiffy because it's easy to apply and dries clear. You brush it on, shape the fabric how you want it, and let it dry.

Plaid Stiffy makes your creations keep their form without going limp or losing shape. But over time and with exposure to moisture, handling, or washing, the stiffness will diminish.

14. Beacon Stiffen Stuff

Beacon Stiffen Stuff comes ready to use in a spray bottle, which makes it handy and easy to apply. It dries clear and doesn't leave marks on their projects. Once you spray it on your project, the fabric becomes hard and keeps its shape well.

This stiffener works great for all kinds of fabrics. Its result is a sturdy finish, but it will diminish over time and with exposure to moisture, handling, or washing.
