Apparently some people had issues with this block, but I thought it was pretty easy. It helped that I have the Tri-Recs templates and didn't have to paper piece the equilateral triangles.
It is freaking hard to do a block when the instructions are in black & white, though. I think over the next month, I'm going to color the pattern so I can follow it better. I screwed up the placement in the HST corners several times.
