I bought a set of Prang crayons at the quilt show. It is a big box with lots of colors. They are softer than other brands so color on cloth better.
I made one sample that I plan on washing to see how it holds up.
It is alot of fun to do. I bought some color books at the dollar store to make a kids quilt with.
The book Faux Applique by Helen Stubbings has some great patterns in it.
She uses pencils but the crayons work just fine.
