OK, This actually should be pretty easy. It's basically the same process you would use for a OBW. you take two 2 1/2 inch strips and sew them together. Then cut 6 60 degree triangles. the triangles are cut reversed, so 3 will have light tips and 3 will have dark tips. Sew the 2 pairs of 3 triangles together, lay the hexes out, then sew into strips.

Skip thru the instructions till you get to the part where the strips are cut into 60 degree triangles.
Make sure you don't join the 2 halves of the Hexagon! it will make it so much easier to construct.
