If you used Flying Geese sewn to a central square ... then I suggest you make some FG in different ways and see which best works for you.
One central rectangle with 2 squares sewn at the corners.
Sewing well starched triangles to a central isoscolese trapezoid. [ 2sides parallel, and the other sides equal in length, though not parallel.]
Using a FG ruler - beware, there are many out there, so try before you buy.
Paper Piecing: Triangles on a Roll has FG, as does a few other comapnies. Your LQS should have some.
Triangulations, I think then also have FG. I haven't used these but some quilters love the program.
Also do a 'net' search for Flying Geese. There are several tutes on the net, including John Flynn's method.
