Stephen, after the stencil was made I spent maybe 3 hours of putting it into the glass. If you do it w/ the dremmel tool like I did then just go LIGHTLY. You'll easily be able to see the results & adjust from there. I was scared to death of breaking the glass, so not really any pressure, just let the tool do the work. If anyone else does this I suggest you practice on a piece of similar glass. I screwed up a few places until I got used to the feel of it. Nothing major, but it's not perfect.
