The Triangle Calculators use finished size and seam allowance to calculate the strip cut size needed for perfect half-square, quarter-square, corner, side triangles as well as custom right triangles created from rectangles. Prefer a method that starts with oversized triangles that are trimmed down to size? Simple adjustments to the calculator will get you the size needed for your favorite method! Once you have your triangle plan in place, input finished sizes into the Yardage Calculator and the automatically generated Cutting Diagram eliminates cutting guesswork! QuiltSandwich app helps avid calculate yardage so they can use the methods they prefer — saving fabric, money and time. QuiltSandwich v.1.10
