When you only need a few flying geese blocks or you prefer the traditional appearance over the dimensional look, this method will serve you well. I also like the accuracy it provides, leaving little if any squaring up to be done.
Here’s the formula:
Sky squares = Finished height + ½”
Geese rectangle = Finished height + ½” x Twice the finished height + ½”
For example, if my finished flying geese unit is 2” x 4”, I will cut my sky squares 2 ½” and my geese rectangle 2 ½” x 4 ½”.
Cut two (2) sky units and one (1) geese unit.
Place one sky square on the left side of the geese unit, right sides together. The square should line up evenly at top, side, and bottom. Draw a diagonal line from bottom left corner to top right corner.
Starting at the outer corner, sew 1-2 threads to the right of the drawn line until you reach the opposite corner. By stitching a thread or two beyond the line you allow for the rollover effect.
Trim away excess, leaving a quarter-inch seam allowance. Press open.
Place the remaining sky square on the right side of the geese unit, right sides together, lining up top, side, and bottom. Draw a diagonal line from corner to corner as shown.
Starting at the outer corner, sew 1-2 threads to the left of the drawn line.
Trim away excess and press open.
Your flying geese block is complete.
If you don’t like the idea of the excess triangles being wasted, draw a second diagonal line 1/2″ away from the first and sew it as well. Then cut between the two sewn lines and you will have a small half-square triangle block to use in a future project.
