I suppose this isn't how they'll be used, but I liked laying them out this way for the photo. They're a little bit big, though, and I may need to fiddle with the seam allowance to get them down to size.
Edited to say: I think the red triangles are too big, period. The instrux said to cut them using the specialty ruler or to cut a 5 1/8" square and then cut diagonally. This makes the red triangle 3 5/8" tall by 7 1/4" wide. I know some of the points get cut off in the process, but I suspect that this is too large. If you have any answers for me, I'm happy to hear them! I posted on Bonni's blog comments a few hours ago but haven't heard back yet.
