I found a new site that I really like and thought I would share. It is called Beaducation. Beaducation has tutorials that are free and some that cost a small fee. They specialize in metalwork so they have tips on stamping, soldering, chainmaille jewelry, and so much more. They also sell supplies for stamping, metals and wire, findings, and again, so much more.
If you like to make jewelry, it would probably be interesting to check this site out. And if you don't YET, it may inspire you to try something new.
