We had a Russian play date at our house this week and we made these suncatchers with kids.
I cut the borders out of construction paper (we tried to do winter theme), taped to it a circle of clear contact paper with a sticky side out and taped the whole thing to the window.
Then I gave kids sheets of tissue paper and they tore it and attached it to contact paper. After everything was filled I put another circle of clear contact paper on top of it and attached another border using a double-sided tape, sandwiching collage in between. I still need to attach a string to ours and it will look so pretty in front of the window.
