I love MGM's videos! They helped me a lot when I first started crocheting.
And my other favorite source for learning was the "Crochet Made Easy
" cd I checked out from the library. I just popped it into my computer, and it started automatically. No need to install. It's like watching a movie, and you can pause or move on to the next section as you please. Videos for all the basics in crochet.
