I recently made an I SPY for a 2-year old. Her parents used sign language with her and she will sign rather than verbalize so this may help her be more verbal. Duplicate blocks? one went in the quilt and the other laminated so it can be used as a matching game....I was just asked if I would sell them a couple they could give their nieces for Christmas gifts. Unfortunately, I'm short on blocks right now...but searching my stash to see if I have the proper prints to join the new swap. Also, these aren't restricted to 2 year olds. I'm making one for my grandson who is 10, but using squares to represent his favorite things (more of a memory quilt).
