can do this quilt without a pattern. Really you can.
1. It's basically a Warm Wishes Pattern, set On Point.
2. The Center row on the rail would be your Flying Geese. (I'd make them first and cut the rest to match whatever size you make them) Or follow this pattern replacing the center row of the rail with the flying geese.
