Hi GinnyG, I'm making the 52". I originally bought 5 balls of yarn of the
one I wanted to use which is approx 1640 yards. I just had to go buy
a 6th ball but I only need it to finished up about an inch of
ribbing on the button band. So can't say exactly how much in total
yardage I have but 1640 plus a bit
Hope that helps you some!
