I can't believe I forgot to post about this this year! I was in Michaels this morning, and saw the Bernat set up with their pink yarn and patterns, and it reminded me.
Go to the Bernat website for their patterns and yarns for breast cancer awareness knitting. Lots of nice stuff.
Here are a few more links with patterns:
