One of my favorite SUPER simple kids crafts is to make puppets out of brown paper sandwich bags! You can do SO many themes with this- monsters, animals, people, etc! It’s simple, all you need is a brown paper sandwich bag, construction paper (or let the kids color their own paper!), and if you’ve got them googly eyes make the kids even happier! I found a pack of 250 at the dollar store for a buck.
(HINT- Let the kids color their paper & bag BEFORE you start glueing!)
