I just found out about this site by reading Quilter's World
They have been doing this for nine years now.
Every month they put up a block to do. You can decide to do the block or not. Your choice. If you decide to do it you put a picture up and the block goes into a lotto. There is a winner every month for the blocks. Sounds like so much fun. I am joining it. Of course I figure you have to give up your block you made if it is a lotto, but that is the whole point. Go to the site and read the rules. I only have read about half so far and sounds like my kind of fun. Probably most quilters kind of fun. :thumbup:
