I've had this activity on our to-do list for a long time, and we finally got around to trying it. It was so much fun, and so easy. We made homemade window clings using colored glue! It takes a lot of drying time, and some patience, but not much else.Mix food coloring into school glue. Outline your shape on a piece of transparency. Maybe making a triceratops and a stegosaurus weren't the best ideas. ;) Allow it to dry for a few hours, then fill it in completely with glue. Allow it to dry overnight.
Peel your homemade window clings carefully from the transparency and stick it on the window! I think the glue I used was a little runny, so the outline isn't solid, but the kids enjoy playing with these. We will definitely do this craft again.
