And here is my Excel pattern. It has all 4 pieces. Each Excel square is 1" finished. So, for example, the middle pieces, the big strip is 8 squares by 3 squares -> finished 8" x 3" -> unfinished 8.5" by 3.5"
Oh, and a fat quarter will yield EXACTLY 4 pieces. With about a 2.5" square to spare. If that. I would plan on it yielding 3 pieces to keep your blood pressure down... trust me on that... :?
