Donna Kato, famed polymer clay artist, teacher and author of some of the best PC books around has gathered a pretty awesome bunch of artists on www.craftedu.com Not just polymer and metal clay but a whole range of other crafts and fine art. There's also a blog http://blog.craftedu.com/
I just bought the tutorial to make this landscape cane by Bettina Welker. It's well written and easy to follow. Needless to say, I havent actually made it yet!!
The tutorials are for sale but there are some freebie intro videos as well.
It's a definite trend to sell tutorials, Etsy are chocker block with them, also check out http://www.claylessons.com/
But if you cant take a class with the real deal, it's absolutely the next best thing
