They have tons of awesome tutorials for making all kinds of different jewelry, and there are new tutorials added all the time! There are also really interesting articles, user forums, tips, and all kinds of other goodies. You can even sell your own tutorials on the site! I could spend hours surfing around.
You do have to pay for the tutorials, but they're pretty inexpensive and they're all rated by difficulty (easy, intermediate, advanced) and have reviews by people who actually used the tutorial.
I can't wait to try some of the tutorials out!!
