I don't know why I didn't think of this earlier - I'll be knitting squares for Laura's Rebuilding Greensburg project until the beginning of August. Perfect lunchtime, car time, mindless knitting, and for a great cause, too! I have a ton of leftover wool and wool blend yarns just calling out for this project. Check out her blog for more info. She is posting updates almost daily, but the initial post for the project is here.
