I think the width is probably 3-1/2 FEET not yards ... you might want to double check. All of your fabric says 3-1/2 yards for the width. Most fabric is 45 inches which is 3-1/2 FEET.
You are right but I think it is too late to change it. I am really confused. I DON"T sew but people who do should realize how it is measured and many watching have stated I should state all measurements. I don't understand why if you know what a yard is. Anyway, thanks for letting me know.
