@Bear,
I actually came out with 9 when I did it by hand (I didn't even see the recommended amounts on the qc site) , calculating that each 6" block has to start as a 9" block (lots of seam allowances).
So I went to double check in EQ, and it came up to the 7.25yds.
How about we we compromise and call it 10 yards of each color?
She's gonna need fabric for the binding and can use some for the back.
