could you cut a 7 1/2" X 2 1/2" rectangle and 2 2 1/2" squares, putting right sides together, place a square at each end of the rectangle. Measure and mark 2" along the bottom, from bottom corners, and 1/4", along the top, from top corners. Draw diagonal line from top mark to corresponding bottom mark on each side. Sew along the lines you drew, trim as you would a snowball, 1/4" from your stiches. Press open "squares" along your seams. You may need to do a little trimming to size, but I think this might work.
