This page has links to blog posts that explain "how I do it." It seems like there is more than one way to do some things with crochet. Magic ring or no magic ring? How do I hide the end tail of yarn after I attach a piece? How do I color change? What are some good ideas for photographing amigurumi? Well...this is just what I do. It's not like the golden rules for crochet =)
Not sure how to change colors when crocheting amigurumi? This might help clarify!
