I use the Fons and Porter mechanical pencils: lead color for light fabrics and white for dark. They brush or wash off beautifully. When I don't have a stencil, just a design, I run it off on paper and poke holes in the paper. I use a powder puff and bath powder to make the design on dark fabric or cinnamon on light. Then I trace with F & P pencils and "puff" the other stuff off. Works for me.
