I puttered the other day with some watersoluble oil pastels and crayola slick stix on Peltex. It worked best when the Peltex was really saturated with water. The colors stayed bright and it was fun to smudge and blend them. The end result looks kind of like wool, or needle felting. I am working on a larger piece with the same technique. Here are a couple ATCs I did, just for me...not to trade as I usually do.
