LOVE this quilt and all the ideas for quilting. I've been on the lookout for a quilt pattern for my 13mo granddaughter, and found some but I think this is IT! I read the directions but she doesn't say what size the background sq is or the finished block and I'm not a math techie (yikes and I quilt?) ... what size is the background sq? I've been even thinking of using my scraps for around the sqs so they wouldn't need to be 2.5insqs ... just thinking...
