Illinois mentioned “I Spy Quilts”. I make these and I put 2 identical blocks in each top so they can play a match game. He’s too young for this now, but you could start collecting fabric. The current one I’m doing is a 9 patch with 5” blocks. The center is a solid fabric. A lot of quilt patterns work for I Spy.

Love all the ideas from this board! Thank you so much. there are definitely several that I will look into making now and some for maybe down the road. Thank you
