When I first came to Phoenix one of the LQS had a class on the different ways to make Flying Geese. This was not one of the ways, but I love it if I have enough fabric.
What was interesting was that each of us had our favorite way that worked best for us. I did best with the one at a time method of starting with a rectangular base and then using the squares for the 2 corners. EX: 4 1/2" x 2 1/2" base and then 2 2 1/2" squares at the corners sewn just inside the diagonal line of each square - for a 4" x 2" FG. Or a 6 1/2" x 3 1/2" base with 2 3 1/2" corners ... etc.
The FG on a roll is nice but not me.
