Using my Robert Kaufmann quilting app, I figured 5 yards should do it for the backing. If it's not enough, I'll piece in some more from my stash. It depends of how the width of the fabric measures after washing, and how much overhang is needed.
This is a great app, free!
Sadly, I bought 6 yards of backing fabric at Paducah this spring, and it wasn't enough! There was only 40 inches of printed fabric between the selvages after prewashing, and an 80 inch width of fabric is not wide enough to back a 79 inch quilt top! I ended up with a 10 inch wide piece of orange fabric pieced into the back. Really a happy accident, since I rather like the way it looks now!
