I also had to Google the TOAR and wondered if the directions contain options, can you cut the 4" squares to make your HST and not cut the 8 1/2 " strips which I think are to be used for the triangles.
Also, I believe there is n error for the red blocks, instructions read cut 3 2"x wof red print and cut 2"x wof cream. I think that we need 3 of each o further cut the 2"units for the 4 patch
