Ur talking about trolls, with a 6 minute response time?? WOW... paint some more stickers kid..
Anywys fireball, there are free and cheap programs(plus, the ol' eyeball) that will seperate your layers better.. grayscale stencils are great with just three colors.
Maybe just try printing, cutting, and spraying for a bit.
If you want a stencil thread that masterbate hasnt run into the ground, u may have to search elsewhere...
