I figured out a DIY version and wanted to share. We worked on these pre-Disney, so I think you can figure out the theme we chose.
Coloring book pages
Plastic slide-in page protectors
Fill the corner of your baggie with glue and add a few drops of food coloring.
Seal the baggie and begin to squish the glue and food coloring together to mix. The kids especially like this part! (Don't worry if the color is a bit pastel, the glue dries clear so the color will be more brilliant once dry.)
Here are our mixed colors:
Choose a coloring book page with a simple design (or use a design you draw yourself) and slide the page into the plastic page protector.
Snip the very corner of the baggie with your scissors.
I like to begin with a black outline first...(BUT I'm not a squirmy 7 year old who needs immediate gratification in the crafty projects. If you choose to move ahead before it's dry, the world won't come to an end.)
Now cut the corners from your other colors and fill in the spaces by squeezing the glue into the black outline. This doesn't have to be perfect! Swirl it! Drip it!
Allow your cling to dry overnight. Once dry, peel the glue design off the plastic page protector and place it on your window! Ta da! (And I believe you might be out less than 2 bucks. Bonus!)
