Button sheep! Cost of craft: $2.50 for a bag of black buttons and white buttons. Leftover cardstock and tacky glue were used too, making it cost effective and calming. Great for kids, and for adults with intellectual disabilities.
This would make a great Fidget Glove - Finger dexterity and a fun clicking sound. (Personally, I would sew the buttons on for durability -- If hot-glued, closely supervise to avoid a possible choking hazard if the button comes unglued.)
