We are the Australian distributors for MercArt. So far we have a small selection of tools and alumimum sheets but I am still learning how to use them. That involves a level of trial and error as I don't have access to the classes run by MercArt in the States. You can use a stamp on the back of the metal sheets or your own design with a permanent marker but the easiest way is to use a metal stencil. If you aren't into hand tooling then you can always use an embossing folder. Her are a few of my practice pieces.
The lesson I learned with this one is to let the filler dry before trying to sand or do anything else as you can knock the puff out of your design. The teapot is a bit flatter now than when I sanded. I used the MercArt filler which hardens as it dries. Don't let the crust fool you as it can look dry but still be liquid underneath. Patience is the key.

If you want to do a class with me on these techniques let me know. I would prefer if you come to me rather than me traipsing all over the countryside. Let me know if the June long weekend would suit those of you who are store owners.
