This is a project I've taught for several years and a favorite of the students. I cut 4.5 squares, the students need 4 white and 4 other colors, I chose Christmas colors ofcourse any will do. Use the template to create 8 nice circles. Decorate only the white with very detailed patterns or scenes. Once finished use the equilateral triangle as a folder. To put it all together I used regular Elmer's, put two sides together (one white, one color), then bend and put 2X2, then 4X4 for a whole Octahedron shape. I punch a hole at the top & string!
