Cool, I'm glad that you guys like them!
The other day I did a folded bead tutorial, its here http://pages.ivillage.com/heatherrrrrr/id14.html
right now I'm working on a mokume gane tutorial. I'd like to do a tut for covering the tins but I don't have any empty tins right now to work on!
About the money, what I used to do is every time I had a birthday or it was Xmas I would tell people that I either wanted gift certificates to Michael's or fimo or sculpey. Michael's sometimes has really good sales where clay is half off, or they have coupons in the paper for 40% off of one item.
Also sometimes on ebay people will sell their leftover clays for pretty cheap when they decide to stop their clay career.
Now I'm working on my real site, which will be at http://www.clayaddiction.com
but I hardly have anything up there yet.
