We made some heart sun catchers today using laminating sheets. You could also use contact paper, but I have found that these are a little bit easier to work with. I cut out a heart shape and then cut out the inside of the heart, leaving about 1/2 an inch border. Then I stuck the heart on the laminating sheet and cut off the excess around the heart. Then the kids stuck little squares of tissue paper all over them, completely covering it. I then punched a hole in the top and tied some cording so we could hang it.
