Moooooooooo!!!

I would use it as a backing on a double sided quilt.

If you buy flat fold bundles from a manufacturer they come folded that way. I just refold. No problem!

If you are looking to make backing -measure the length of the back and cut cut another piece the same way then split in lengthwise and sew each half onto the long center piece-on 44 wide it wil give you 88 wide when done minus seams and selvadges-hope the makes sense
