This question comes up a lot on Metal Clay Gallery, a yahoo group you can find at: MetalClayGallery.
When you join Metal Clay Gallery, you should also sign up for Metal Clay Gallery 2, our overflow site for photos, and Metal Clay Market, a special place just for buying and selling. MetalClayMarket.
So where else? Precious Metal Clay and Art Clay Silver are both expensive, so people are naturally hesitant to dive right in.
Another great place to learn more is MSchindel’s Squidoo Lens on Metal Clay.
You can also find MSchindel’s terrific tutorial on weaving with metal clay paper at my site, CreativeTextureTools.com, under Resources.
I have created a list, Beginning Tools for PMC, in response to the question, what do I need to get started? You can find it at my site under resources.
That should keep you busy for a while! If you have a question, please post a comment and I’ll do my best to answer. Thanks.
Update, September 22, 2007
I’ve added more Squidoo Lenses of interest to folks doing metalsmithing and metal clay. Check out Top Ten Tools for Metal Clay. Links to even more of my Squidoo Lenses are on the Links page.
