I’ve used two parts acrylic paint to 1 part craft medium. This makes your finished project soft, washable and permanent. Keeps the colors bright, and doesn’t chip or peel as if you were using regular acrylic paint.
use freezer paper to create a stencil, iron it on and stencil on fabric paint with a stiff brush. pull off your stencil and wait for it to dry. Pick an easy print out of your favorite fandom, create your own shirt!
