I just watched the demo by Eleanor Burns for her flying geese. Looks like a lot of work to me. I use the method of folding the side squares on the diagonal, one pin to hold in place, then sew on the pressed line. You can either leave the extra fabric there or cut it out depending on what you like. I think it was Mary Ellen Hopkins who showed this method. I also like, I think Ricky Tims method, where you put a square of fabric in between two others and wind up with a 3 dimentinal flying geese. Sure with some googling you'll find what you like best.
