Kirigami Triangle Window Decoration
This triangle window decoration requires only a sheet of paper and a pair of scissors. The resulting project can be glued in front of card stock to make a one-of-a-kind greeting card. Alternatively, the decoration can be taped to a window; the sun shines through the layers of paper to make a great design. This project can also be done with a rectangle or a square piece of paper.
