14-gon borders marked with the same number and color are stitched together. (They correspond to the same line in the Klein quartic.)
The 9 heptagons cut by borders are colored. 7 heptagons are cut in half, and 2 are cut in 7 parts. (The latter are on the 14-gon vertices, and are marked in brown and beige.)
