Originally I gathered about 200 blocks, but not sure at this point how many there are. Can't remember who sponsored it, but someone had a bunch of I-spy block swaps and I got in on one--with the result of some really cool blocks. Plus my dear friend Shirley, gave me a lot of blocks left over from a quilt she'd done awhile ago. Hers were a different size, but serendipitedly it worked out well with 7 of hers equalling the length of 9 of mine!
The back will have some more blocks that didn't make it on front. I also have some really fun material to put on back with those. And I'm making a list of all blocks that will be laminated and put in a pocket on the back so my girlie girls and boyly boys can search for things when they're playing on it. And, of course, it'll be nice and warm to snuggle under.
