Now, to make one flying geese unit, place a Color 1 2-1/2" (2")
square right sides together atop a Color 5 2-1/2" x
4-1/2" (2" x 3-1/2") rectangle, with outer
edges aligned. On the back of the top square lightly mark the
diagonal. Sew on this diagonal marking. Cut off the excess seam
allowance. Press the remainder towards the corner. Repeat this with
another Color 1 square on the other end of the rectangle. Make one
more Flying Geese unit in this color combination...
