Fabric Paint & Stencils

Anyone out there with experience using fabric paint with a stencil? I've done it before (after all, I was a Girl Scout for six years), but not in a long time. Also, I'm pretty sure that was on a t shirt. What I have in mind this time is using plain quilting cotton.

Damn, it's both wonderful and awful when I get these ideas in my head, and they have to be done now, now, NOW!
