How to keep polymer clay from sticking to molds, cutters, surfaces and rollers.

Well, water works great.  It doesn't hurt the clay to get it wet.  However, my favorite is CORN STARCH!  It works just like flower does to keep you pie crust from sticking.  I usually brush it on the surface of the clay with a paint brush.  It's so weird, because I could swear I was working with flower.  This has made working with the clay so much easier!
