Monoprints made with acrylic paint printed onto fabric is a quick and easy surface design technique. It's important to use a paint that is fairly thick (I like to use fluid acrylics). I dab, smear, drop, paint onto an acrylic or glass sheet - using my fingers, pencil eraser, or any tool that is handy I create a design. Print onto fabric - let it dry - iron to set - that's all there is to it.
