This page is continuously adding new crochet patterns. Lots of baby items to make, too! I promise I will only post patterns that I myself have tested and approve of.
Diagonal Square: http://www.ravelry.com/patterns/library/free-smoothfoxs-diagonal-box-stitch-square-6x6 - this is a great square, great texture, really appealing. I'd rate it at intermediate level. You must be a Ravelry member to see this pattern, but membership is free and they never ever email you.
Basic Beanie: http://crochet.about.com/od/easy-crochet-patterns/a/simple-crochet-beanie-hat-pattern.htm - a super-easy hat to make!
www.ravelry.com - Searchable patterns, forums, and an excellent organizational tool for all your knitting, crochet, and spinning projects.
