Beth's Videos for Crochet
Here is my favorite place to go for refresher courses (or for new crocheters to learn) or ideas to crochet. Beth is a wonderful crocheter and has so many CAL's as well. As far as I can tell she has been posting crochet and some knitting videos (mostly crochet) for about 6 years. There is a mountain of information for new and experienced crocheters alike.
I wanted to add a few things that you can learn from Beth's videos and this is just to name a few
Tunisian stitches
basic crochet stitches
lattice shell stitch
Puff stitch
bobble stitch
there is lots more to see and learn
