How we worked it out

Updated as you change the numbers.

  1. Add 1/2 in for squares and rectangles, 7/8 in for half-square triangles made two at a time, and 1 1/4 in for the large flying-geese square. Pieces per strip = width of fabric ÷ cut width.

Method and assumptions

These are the standard cutting allowances for 1/4 in seams; many quilters cut HST squares a little larger and trim to size. Yardage includes 4 in for straightening.
