Flying Geese Calculator

A flying geese unit is a rectangle twice as wide as it is tall, with a large triangle (the goose) in the middle and a small triangle (a wing) on each side. They appear in Sawtooth Stars, borders and many traditional blocks.

Width is twice the height.

Method

Cut 2 goose squares and 8 wing squares.

Finished goose4 x 2 in
Goose squares (body fabric)2 x 5 1/4 in
Wing squares (background)8 x 2 7/8 in
Unfinished goose4 1/2 x 2 1/2 in
Trim toNo trimming

A one-way print on the goose fabric will face four directions with this method.

Enter the finished height of your geese (the width is always twice the height) and how many you need. Choose the no-waste method, which makes four geese from one large square and four small ones, or stitch and flip, which makes one goose at a time from a rectangle and two squares.

Worked example: 8 geese that finish at 2 x 4 inches

8 flying geese, 4 x 2 in finished (4 1/2 x 2 1/2 in unfinished).

  1. No-waste, exact: body square = 4 + 1 1/4 = 5 1/4 in; wing squares = 2 + 7/8 = 2 7/8 in. Each set makes four geese, so cut 2 body squares and 8 wing squares.
  2. No-waste, oversized: body square 5 1/2 in and wing squares 3 1/8 in, then trim each goose to 4 1/2 x 2 1/2 in.
  3. Stitch and flip, exact: 8 rectangles of 4 1/2 x 2 1/2 in and 16 wing squares of 2 1/2 in.

Result: 2 squares of 5 1/4 in and 8 squares of 2 7/8 in (no-waste, exact).

Flying geese formulas

  1. Finished width = 2 x finished height. Unfinished size = finished + 1/2 in each way.
  2. No-waste (four at a time), exact: body square = finished width + 1 1/4 in; four wing squares = finished height + 7/8 in. One set makes four geese.
  3. No-waste, oversized: body square = finished width + 1 1/2 in; wing squares = finished height + 1 1/8 in; trim to the unfinished size. This is the default in QuiltLab's block construction recipes.
  4. Stitch and flip, exact: body rectangle = (finished width + 1/2) x (finished height + 1/2); two wing squares = finished height + 1/2 in per goose.
  5. Stitch and flip, oversized: every starter piece 3/4 in larger than finished, then trim.
  6. No-waste sets = geese needed / 4, rounded up; extra geese are spares.

Assumptions

  • Seam allowance is 1/4 in.
  • Geese are 2:1 (twice as wide as tall), from 1 x 2 in finished upward.
  • The no-waste method turns the body fabric four ways, so a one-way print will point in different directions. Stitch and flip keeps it upright.
  • Every formula is checked in the test suite against a geometry simulation of the sewing and cutting, the same check QuiltLab uses for its block construction recipes. A simulation is not a sewn sample: make one test goose before cutting everything.

How to make no-waste flying geese (four at a time)

Make four 4 1/2 x 2 1/2 in geese from one 5 1/2 in square and four 3 1/8 in squares.

  1. Draw a diagonal line from corner to corner on the wrong side of each wing square.
  2. Lay two wing squares right side down on opposite corners of the body square, so the drawn lines form one continuous diagonal. The small squares overlap in the middle.
  3. Sew 1/4 in from the line on both sides, then cut on the line. Press the wing triangles open, away from the body fabric.
  4. On each half, lay one more wing square right side down in the remaining body corner, its drawn line running from that corner to the gap between the two wings.
  5. Sew 1/4 in from the line on both sides, cut on the line, and press the new wings open. You now have four geese.
  6. Trim each goose to 4 1/2 x 2 1/2 in: line up the ruler's centre line with the point, lay its 45-degree lines along both wing seams, and keep 1/4 in of fabric above the point.

Frequently asked questions

What size squares do I need for no-waste flying geese?

For exact geese, cut one large square at the finished width + 1 1/4 in and four small squares at the finished height + 7/8 in. For 2 x 4 in geese that is one 5 1/4 in square and four 2 7/8 in squares, which make four geese.

Which flying geese method wastes the least fabric?

The no-waste (four at a time) method, as the name says: nothing is trimmed away when you cut exact. Stitch and flip cuts off two corner triangles per goose, though they can be sewn into bonus HSTs.

Should I make flying geese oversized?

If your points tend to get cut off, yes. Oversized starters give you room to trim each goose with the point centred and exactly 1/4 in below the top edge.

Can I use a directional print for the goose?

Use stitch and flip. The no-waste method makes each goose from a different edge of the big square, so a one-way print ends up facing four directions.
