To make each of these super easy butterflies first you have to take a square sheet of colored paper. Then fold it in half diagonally so that you get a triangle. Open the paper and place it in a way that you will get one upper and one lower triangle. Start making pleats in the paper starting from the centre to the corners of both the triangles one by one. Do the same steps to another piece of paper and then join them together in the centre with a thread. Detail the butterfly with pipe cleaner. Make more and decorate your rooms.
If you want you can try different shapes too like this one. Enjoy crafting!
