 1. Divide window width by 3 to get stacking distance2. Add window width with stacking distance and 12"3. Multiply the total amount by the desired FULLNESS requirement4. Divide the total amount by the material width to get the required panel fullness5. Add window height with desired hem and header length 6. Multiply total length by panel fullness to get total square footage7. Divide total square footage by 36 to get total square yards
