By painting fabric with dye, you can create beautiful watercolor effects by blending and bleeding colors. It can be as simple or complex as you want. I actually like how the back side turned out better because there was more bleeding and the plastic under it created some interesting effects. You can combine this painting method with other techniques like batik dying or create a multi colored ombré.

Make sure your work space is covered with plastic or something to protect it from staining. I’m also putting down layer of plastic wrap a little larger than the piece of fabric. This is so I can easily wrap it up in the plastic to microwave later.
For best results, use a fabric made from natural fibers like cotton, and pre-wash the fabric. Soak it in warm water while you mix the dye.
Heat water to near boiling and pour into cups. Shake the dye, add it to the water and stir. The more dye you use, the darker and more saturated the color will be.
Squeeze out excess water. If you leave the fabric pretty wet, it will bleed more, or if you use dry fabric, the bleeding will be minimal.
Lay the fabric flat on the plastic. Use a foam brush or paint brush to apply the dye. A large brush will cover bigger areas or use a small brush or eyedropper for more detail.
Using fixative is optional but recommended to help preserve the color. Attach a spray nozzle to the fixative or put it in a spray bottle and saturate the fabric. Let it sit for 20 minutes.
Rit dye loves heat, so to further set the color, I’m going to microwave it. Cover the fabric with another layer of plastic wrap and fold it up. Press the edges of the plastic together to seal it.
