Just a follow up - I Goggled the book and found the author's website. I contacted her via email and received a response less than 20 minutes later! Not bad for a Saturday night. The template was wrong (yeah, it wasn't me!). However, I'm still stuck with 96 trapezoid units that are too small for the triangles. I replied back to her asking her to help me calculate what size to cut the triangles down to, since I don't have enough fabric to recut the trapezoids.
