I started out by sorting the triangles by color. Then I arranged them in the rainbow like color pattern pictured below.
Next I pinned them to the equator line of a 7cm diameter smooth foam ball.
Then I made another set of triangles like the in the first picture. I flipped them so the bottom was now the top. Then I pinned them in the pattern pictured below to the ball. The numbers and letters correspond to matching colors.
Once all my colored triangles were pinned my ornament looked like this from the top and bottom.
I then added 3 silver triangles to both the top and bottom of the ball. The triangles on the bottom are spaced closer together than the ones on the top.
Next I filled in the remaining empty spaces with clear iridescent glitter glue.
Last I added a silver and white bow to the top.
This was so easy to make and looks great on my tree.
