Use a poster board, any kind of squared wood for bottom with edges & Christmas lights; cut any size holes in posterboard; Christmas lights sit on bottom of square; shape the poster board & use a thin line of hot glue to hold them together = nightlight.
Blow up a balloon, cover it in doilies using a craft glue. When it's dry, pop the balloon & you have an awesome decoration. Bet you could use it as the lampshade on a small pendant light, too. Great-gramma's and my MIL's doilies may find another use.
