Ok I misunderstood...save the info I just sent for backing
if the pattern says 7 yards for BACKGROUND that works out to 9072 square inches...36 by 36 by 7
in the wide back one yard is 36 by 108 which I think works out to 3888 sq inches...so 9072 divided by 3888 is 2.3 yards of the wide fabric...I think this is correct...it works out to the same square "inchage"....I just made up a word I like...
