I found this idea on www.frugalfamilyfunblog.com.
It is a cheap and fun craft for any age!
Cut a shape out of construction paper and lay on the sticky side of contact paper.
Stick tissue paper confetti on the contact paper.
To make the tissue paper confetti cut a bunch of very small pieces of tissue paper! :)
Cover with another piece of contact paper.
Trim the edges and hang!

They look so pretty in the window!
