Donna, since I'm using chunks of border and sashing I decided not to use for what it was cut for, it's hard to tell what kind of yardage I've used.
However I really doubt this is going to use more than 3-4 yards.
So I did some math- 6.5" block would use 42.25 sq inches, 140 blocks would be 5915 sq inches total. Assuming a yard is 40" wide, that would be 1440 square inches. So that works out to be 4.1 yards. And only one or two blocks will use a lot of background, so it should not take over 4 yards.
Since I've no new blocks to share, here is my cutting table in all it's "glory"
and my growing pile of blocks waiting to be sewn
