This was written up for the TemariKai pattern section (Direct link here). Basically you stitch the large triangles (20 of them) first interlocking them at the pentagon centers, then stich the triwings (20 of them) on each icosahedral triangle again, interlocking them with the other elements.
I used an entire skein of each color. I really like this pattern. Will write up for TK. This one is larger than #060204 and the negative space worked out a bit nicer. Definitely do not do on a smaller mari without adjusting thread size. I think the large triangles are tetrahedral but I'll need to play a bit to be sure.
