This is a super easy gift idea that even your smaller kids can make: Magnets! My boys have some magnet boards in their rooms so I had my youngest boy make some magnets that they could use to hang their artwork. We ran to Hobby Lobby and I let him pick out some of the pre-painted wood pieces. He really put a lot of thought into each one. We also decided to get a bag of the polished stones. (Buttons would also be a really fun option!)
We later hot glued some strong magnets to each item. Like I said, super simple but something my son was really proud of and excited to give!
