Cut WOF strips at your triangle height, then sub-cut into triangles. Efficient for equilateral or isosceles triangles.
Formula
Triangles per strip = strip length ÷ triangle base. Total yardage = strips needed × strip width ÷ 36.
Example calculation
From a 42" WOF strip, you can cut about 10 triangles with 4" base or 8 triangles with 5" base.
Results are planning estimates. Always round up when buying fabric, especially for directional prints, shrinkage, fussy cutting, or cutting mistakes.
