Fabric paint is a useful tool for customizing clothing, sheets, bags, and much more. If you're like me, you don't want to be limited by just the colors at the store, you want much more! Most fabric paints only work on a single type of fabric, and that can make it difficult to find what you want.

This Instructable will show you how to make your own custom fabric paint. You can customize it by color, fabric type, etc. to make a paint that will work for whatever you need!

Here is What You Will Need:

Acrylic Paint
Acrylic Medium (Liquitex mediums work great, I used a transparent gloss medium)
Container with Tight Fitting Lid
Fabric for Testing (You want something the same or similar to what you will use your paint on)
Iron / Ironing Board
Foam brush (Paint brushes work well in a pinch, but I've found foam brushes work better)

Step 1: Mixing Your Paint

The biggest difference between normal fabric paint and acrylic paint is that acrylic paint is much thicker, which can cause flaking of the paint and an uncomfortable stiffness to the fabric. While you could thin it down with water or isopropyl (rubbing) alcohol, this can cause it to seep through the fabric instead of staying on the outside.

The easiest way to make a fabric paint from a basic acrylic paint is to thin it using an acrylic medium. I used a transparent Liquitex gloss medium which works well for light colored fabrics. If you want to use your paint for darker colors, it would be better to use an opaque gloss or matte medium.

Mix equal portions of your acrylic paint and your acrylic medium to thin out the acrylic paint to the appropriate thickness.

Step 2: Testing Your Paint

Now, not all acrylic paints are the same, and depending on what fabric you are using it on the paint might need to be thinner or thicker to get the correct look.

Test your paint using swatches of the same or similar fabric to what you plan on using your fabric paint on. As you can see, my paint shows up much more vividly on a light colored fabric.

If your paint soaks through the fabric, you may need more acrylic paint in it. If it dries to an uncomfortable stiffness, then it may need more of the acrylic medium.

I usually heat-set and wash my test sample before tweaking the fabric paint, as it may change the feel of the fabric. For me, the painted fabric usually gets a lot softer after heat-setting and washing.

Step 3: Heat-Setting Your Paint

Once the paint has completely dried, you can heat-set it by ironing it (set your iron on a medium temperature) for 4-5 minutes. Do not use steam.

Once it is heat set, wash your fabric with the same detergent you plan on using on painted items. For my samples, I usually just throw them in with a load of laundry of the same type, but you can also wash it by hand.

I've found that tumble-drying rather than hanging to dry also helps to soften the paint and make it feel more comfortable.

If you find your paint is still too thick after heat-setting and washing your sample, then add a bit more medium and test it again.

Step 4: Use Your Paint!

Congratulations! You just made your own fabric paint. There are now countless colors that you can make now that you are not limited to the colors at the store. Customize your clothes, pillows, etc. in a whole new way!

I started out by just creating a basic heart t-shirt, but the possibilities are endless!
