Hi everyone,
I need some opinions. The first picture is the quilt top I made for my neighbor's GS. I am now getting around to making the backing for it. The second pic is all the extra fabric and all the scraps from this quilt. I was going to use it for the backing but now I'm thinking it may be better used as a quilt top that, when finished, could be donated to a charity. So quilt back or quilt?

Thanks to all who respond.
