Thanks for the input. I think the yardage is the way to go. I'm going to work on getting it ready to sell. It's a big process that's for sure.
My guild is also going to be doing a lot of charity quilts which I don't mind using the fabric for. Most of the women in my guild will donate a block or two but won't donate batting or backing fabrics. This stash could go a long way for charity quilt backings...
