This document provides instructions for making a Christmas tree decoration using 13 dodecagons of different sizes colored in a chromatic progression of shades of green. The dodecagons are cut into segments and folded to form concentric circles, then glued together and decorated with stars of decreasing size to resemble a Christmas tree.
