What are Templates?

Ah, goodie.  Stencils are a good thing in my mind.

and awesom new avitar hans.

Yeah, they're cut-outs... A better word for them is "stencils"...

You've got the idea. They're usually plastic, sometimes metal. It's best to not spray over them because it's not likely that you can hold it perfectly still over the model. The best way is to use the template to cut out a mask from tape. Stick your mask on the model, and then spray over that.
