ATCs and beyond!

First question was, what is an ATC, ok I got it, then came row houses, moo cards, inchies, deco books, gothic arches, arches, triangles ,Zentagles. The list seems to go on and on in the ATC arena. I always figured, the best way to learn something, is to just jump right in. So I sign up, I research and I create. I now know what all these things are and how to make them. I thought it might be an interesting idea for a class, we could make one of each and everyone would leave with a finished portfolio of the listed items plus templates to make more! What do you think?
