These little hand bats make cute keepsakes. Trace your child's hands onto black construction paper and cut them out.

It's so fun to pull the hand bats out from previous years and look at how they have grown.
This idea came from our local kid's museum. Musings Of Me also makes cute little bats like this, but with paint
