Here's a version of the shoebox guitar activity (instructions at link) from Sunny. We used a sturdy little giftbox and some paper straws. Auggie had some trouble with the elastic bands so I did that for him, and I cut out the hole with an exacto knife. I think within a year he could tackle this project on his own with safety scissors, but not today. He really loves colouring on black paper so lucky for us we had a black gift box in the closet.
