Now, to make one flying geese unit, place a
Color 2 small square right sides together atop a Color 1 rectangle,
with 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 center. Repeat this with
another Color 2 square on the other end of the rectangle. Make four
flying geese units in the same manner...
