Calculate the final yardage To calculate the final yardage, multiply the number of strips by the length of each strip. In our examples: for unmatched fabric, this would be 12 X 98″ = 1176″ for matched fabric, this would be 12 X 104″ = 1248″ Then divide by 36″ to convert to ya...
We already know the total inches we need because we figured out how muchcordingwe need (the inches, not the yardage). But, before you start cutting random strips of fabric, you have to figure out how wide they need to be. Of course, we have a formula for this too!
