Question: how to calculate yards of fabric for cushions?
Answer: 5″ + 9″ equals 14″, thus you will multiply your adusted length of 74″ by 1.1 for a total of 81.4″. Divide 81.4″ by 36″ for a total of 2.26 yards. Multiply 2.26 yards by 3 cushions, equaling 6.78 yards. Now multiply your adusted length of 37″ by 1.1 for a total of 40.7″.
