Where is the best place to buy engraving templates/stencils and what should I buy?

I bought one of those little rotary tools and I want to use it to put my name & address on some things. I want it to look neat so I want to use some kind of stencils for making letters. Somewhere (?) I saw a mention of small metal templates of letters and numbers to use when engraving. I think that's what I need. My questions are: what do I ask for and where is the best place to buy them?
