Knitting Block-a-thon

Not that I need another reason to knit or crochet, but I found one.  Casting On Love is holding a block-a-thon contest.  Knit as many 9" blocks as you can in the month of march.  But the best part, is it's all in the name of charity!  I've been looking for a way to get rid of a lot of my stash.  How perfect is this?  I'm not saying I'll be the contest winner.  I'm DEFINITELY not saying that, but I like the idea.  Why on earth haven't I come across this before?
