I just came across http://www.knittinghelp.com - can't believe I'd never seen it before. It's the best collection of knitting videos I've seen anywhere online, and they're all *free*. If you're a beginning knitter or you've always been confused by increases or decreases, this site is a definite must-see.
I LOVE www.knittinghelp.com!! It has been so helpful with all the increases and decreases I've done with my first sweater and with understanding how to wrap and turn for my MD scarf.
I'd never have learnt how to graft if not for knittinghelp.com. All the unrealistic photos in the books were useless, but her technique of doing it was a big "aha" moment for me.
