Felt Snowman in a Bag - A Build Your Own Snowman Felt Activity for Kids (in a bag). this would make a great Christmas gift (I would include Olaf's facial expression in addition to the traditional snowman options)
Popsicle Stick Puzzles - An easy storage idea is a plastic baggy. These puzzles would be great to put in a diaper bag or purse to pull-out when you’re on-the-go and need a quiet activity! Could also add the little magnets to the back for fridge fun.
