More busy bag ideas... I saw this on Pinterest, but specifically or rather sophisticatedly was done by Powerful Mothering. Her kid did some very sophisticated shapes, which are more complex and impressive.
Easy enough, supplies: Jumbo craft sticks, I chose the colored ones. Velcro both hook and loops, tape one on each end of the stick. I only did one side, but you're welcome to both sides.
Great way to teach little ones shapes.
Or have them attempt to make their own. (no my kid did not make that, but that is his favorite shape). Easy enough, pack it on the go. Of course, expect a few to disappear too.
