Take a 20×20 cm, 2-3 mm thick felt material, a ruler and an Exacto knife. Follow the instructions on the photos below. Draw the symmetrical lines using a marker, and then make the cuts with the knife where the photos indicate. The diagonal line should stay untouched. Next, fold the individual slices from the inside in a mirror-like fashion, and fasten them together with glue or staples. With this technique, you can make beautiful 3 dimensional ornaments that can be made into a chain too. All the rest is up to your imagination.
