I found a local wool shop that does day courses and it was brilliant, £35 for tuition in a small group, all having fun, lunch and materials. At the end we could all do the main stitches and turn. I did a second day doing granny squares and from that most things are now possible. I have a Rowan book of how to crochet too which is okay but I found you can't. Beat facing someone show you as some things I just couldn't get from the book. Do you know someone local who would teach you? God luck, I'm now hooked (pun intended).
I'm trying to learn to crochet, youtube has not been my friend! There was a thread here a few weeks back with some good links and I can't find it now, one with links to Aussie or British tutorials which were quite to the point.
I can't knit very fast and would like to produce a few blankets at some point so crochet seems my only option!
