Flying Geese Calculator — 4-at-a-time & 2-at-a-time

Flying Geese Calculator

NZ spelling. Shows inches for cutting and metric (cm/metres) for reference and buying.

Inputs

A flying geese block has one larger triangle (the goose) and two smaller triangles (the sky).

Finished width is always 2 × height.
Most quilting cotton ≈ 42" usable.

Method Cheatsheet

4-at-a-time (No-waste)
Cut sizes:
  • Big square (goose body): finished width + 1¼" (– cm)
  • Small squares (sky): finished height + 7/8" (– cm)
2-at-a-time (Stitch-and-flip)
Cut sizes:
  • Rectangle (goose body): finished width + 1/2" × finished height + 1/2" (– cm)
  • Squares (sky): finished height + 1/2" (– cm)
Formulas use standard quilting allowances. Always test one block if your ¼" seam varies.

Four-at-a-Time Method

Cut Fabric Pieces

Cut 1 large square (the “goose” fabric).

Cut 4 small squares (the “sky” fabric).
Use the calculator above to determine sizes.

Sew First Diagonal

Draw a diagonal line on the back of two small squares.

Place them in opposite corners of the large square, right sides together, overlapping slightly in the centre.

Sew a ¼″ seam on both sides of the drawn line.

Cut along the line to make two units.

Add Remaining Squares

Place another small square on each unit, right sides together.

Draw a diagonal line on the back of each small square.

Sew a ¼″ seam on both sides of the line.

Cut along the line.

Press & Trim

Press seams towards the sky fabric.

Trim units to the size given by the calculator.

You now have 4 Flying Geese units.

Two-at-a-Time Method

Cut Fabric Pieces

Cut 1 rectangle (goose fabric).

Cut 2 small squares (sky fabric).
Use the calculator for sizes.

First Corner

Draw a diagonal line on the back of a small square.

Place it on the rectangle’s left corner, right sides together.

Sew on the line, then trim seam allowance to ¼″.

Press sky fabric outwards.

Second Corner

Repeat with the second small square on the rectangle’s right corner.

Sew, trim, and press outwards.

Finish

Square up the unit to the calculator’s measurement.

You now have 2 Flying Geese units.
