Flying geese cutting chart, no waste method
One large square of goose fabric and four small squares of sky fabric make four geese with zero scraps. The standard formulas: large square = finished width + 1 1/4", small squares = finished height + 7/8".
| Finished goose | Large square (1) | Small squares (4) | Yields |
|---|---|---|---|
| 1" x 2" | 3 1/4" | 1 7/8" | 4 geese |
| 1 1/2" x 3" | 4 1/4" | 2 3/8" | 4 geese |
| 2" x 4" | 5 1/4" | 2 7/8" | 4 geese |
| 2 1/2" x 5" | 6 1/4" | 3 3/8" | 4 geese |
| 3" x 6" | 7 1/4" | 3 7/8" | 4 geese |
| 4" x 8" | 9 1/4" | 4 7/8" | 4 geese |
| 5" x 10" | 11 1/4" | 5 7/8" | 4 geese |
Which flying geese method should I use?
The no waste method is the efficient favorite: nothing hits the scrap bin, four identical geese arrive per batch, and the formula above handles any standard 2:1 goose. The traditional stitch and flip method cuts a rectangle and two squares per goose; it wastes the flipped corners, but it works at any width to height ratio, lets every goose use different fabrics, and the trimmed corners can be sewn into bonus half square triangles before you cut them away.
Why flying geese are 2:1
A flying goose finishes twice as wide as it is tall because the goose triangle is a quarter square triangle: its long edge runs the full width and its point hits the exact center of the top edge. Blocks like Dutchman's Puzzle, sawtooth stars, and most pieced borders depend on that proportion. If a pattern asks for an unusual ratio, the traditional method handles it; just enter the width and height your pattern gives.
Sources and methodology
No waste method: 1 large square = finished width + 1 1/4", 4 small squares = finished height + 7/8", yielding 4 geese per batch. Traditional method: rectangle = (finished width + 1/2") x (finished height + 1/2") with 2 squares at finished height + 1/2" per goose. These are the standard published quilting formulas, cross-checked against multiple independent references. Unfinished units measure finished + 1/2" in each direction.
Flying geese questions, answered
The point of the goose should sit exactly 1/4" below the top raw edge, so the next seam grazes it without beheading it. If points keep vanishing, the usual culprits are a seam allowance running fat or units that were not trimmed square. Sew with the goose unit on top so you can see the point and steer the needle just beside it.
No, the geometry only works when the finished width is exactly twice the height, because the four geese are born from the diagonals of a square. For tall, skinny, or stubby geese, switch to the traditional method, which is just a rectangle with two corners flipped and does not care about ratios.
One quarter of the block's finished size wide. A 12" sawtooth star uses geese finishing 3" x 6", an 8" star uses 2" x 4" geese, and so on: the goose width equals half the block, the height a quarter. Enter those finished numbers above and the cutting sizes fall out.
A light trim is worth it even with exact cutting, because the diagonal seams invite tiny wobbles. Square each unit to finished size + 1/2" in both directions, keeping the point 1/4" from the top edge. Ten minutes of trimming buys a whole quilt of sharp points.
