I haven't come back to this thread in a few days...but just in case, I will answer the two questions. The pattern is from this site
http://www.quilterscache.com/S/Squar...es2Block.html. It is free and only has two pages.
The grab bags were from our quilting guild. The charity quilt committee members (we call them comfort quits) just bagged up fabric and we took them as a challenge. We could look in the bags, but there was no time to pull fabric out and see what was really there.
I am working on my next quilt from a grab bag, and this one has not been so much fun, but I will conquer it! :)
