When I read #3, it made more sense to me than the others. Seems like it is just rectangles 2.5" x 4.5" with 2.5" squares attached on the corners & then trimmed. I'm going to ignore the "bonus triangle" part & just worry about getting the diamond rectangles done. My main problem will be remembering to attach the squares correctly so the diamond is still a diamond when I'm done. Aaahhh, the joys of quilting. Have a good time w/it anyway.
