I have to tell you--I just did an I spy using 2.5" squares for a baby shower gift.--think it was 11 squares x 13 in a checkerboard pattern so a little over 70 squares of I spy and 70 a neutral. My 18 month old GD saw it and loved it--wanted it for herself. Didn't put a batting in it, but a minkee on the back. Now to use u those 5 inch squares for the last swaps!
