Cutting dimensions for any flying geese unit — standard 3-piece method and no-waste four-at-a-time.
Flying Geese Formulas
Standard method: Background squares = finished height + 7/8″. Center rectangle = (finished width + 1/2″) × (finished height + 1/2″).
No-waste 4-at-a-time: Large square = (finished width × 2) + 7/8″. Small squares = finished height + 7/8″.
Flying Geese Cut Size Reference
| Finished Unit (W×H) | Bg squares (×2) |
|---|---|
| 2″×1″ | 1-7/8" |
| 3″×1.5″ | 2-3/8" |
| 4″×2″ | 2-7/8" |
| 5″×2.5″ | 3-3/8" |
| 6″×3″ | 3-7/8" |
| 8″×4″ | 4-7/8" |
| 10″×5″ | 5-7/8" |
| 12″×6″ | 6-7/8" |
Frequently Asked Questions
How do I cut flying geese pieces?
For the standard 3-piece method: cut the center rectangle at (finished width + 1/2") × (finished height + 1/2"). Cut two background squares at (finished height + 7/8"). Draw a diagonal on each background square. Place on opposite corners of the rectangle, sew on the diagonal, trim, and press open.
What is the no-waste flying geese method?
The no-waste (four-at-a-time) method uses one large square and four small squares. Large square = (finished width × 2) + 7/8". Small squares = finished height + 7/8". Place two small squares on opposite corners of the large square, sew, cut, then add the remaining small squares. You get 4 flying geese units with no wasted fabric.
What is the standard flying geese proportion?
Standard flying geese units have a 2:1 width-to-height ratio. A 4×2" finished unit is the most common. The unit looks like a triangle (the goose) pointing right, with two smaller triangles (the sky) on either side.
How many flying geese for a quilt border?
Divide the border length by the finished flying geese unit width. For a 60"-wide quilt with 3"×6" units (pointing sideways), you need 60 ÷ 6 = 10 units per side border. Always check that the number divides evenly before cutting; adjust the finished quilt size or add corner squares if needed.
