I wasn't sure how it would work out--trying to be crafty while he was awake--but surprisingly enough, he was really excited to find the colors as I called them out. He'd pick a pompom, hand it to me and then I would thread it.
So, it doubled as a learning/color recognition activity. That's a win in my book!
Looking forward to making a Christmas one and valentines one. Maybe by valentines day we can work on some pattern recognition.
