DIY painted block puzzle craft for kids- each set of blocks could make 6 puzzles (paint colors different per shape to make it easy, same color in different shades for medium difficulty, or all puzzles the same color for difficult)
Homemade Bath Crayons from Little Crunchy Mama: Buy some glycerin soap at a craft store. Melt it in the microwave, add food coloring, and pour into an ice cube tray. Takes about an hour to cool completely, then pop out of the mold and you have crayons!
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.
