oh my suck detail for chairity quilts........what difference does it make if the back matches. I don't put ugly fabric on the backs but something that would not be really out of place.
I do match the binding and try to coordinate a bit with the backing.
About chairity quilts::::: someone is always misguided if they think the recepient really cares about matching backs...
My story is a group that wouldn't pay the part of postage for a box of fabric because some of the fabric were blends and they only used cotton. Now this was a group in south Florida. So they paid only for the portion that was cotton. They didn't get any more fabric from me.
