If the quilt is beautiful, the colors just sing and the pattern outstanding, then save what you can. If it is ordinary, as it sounds it is since it has already been deemed as worth only to be used to save on batting costs, why waste the effort on what was evidently just everyday bedding? The women who made quilts as their bedding back in the 1800's and early 1900's were very practical. Everyday bedding made to keep you warm and stacked as many as needed on a bed were used under the one that was made to be pretty and shown, or under a hand woven wool coverlet. My grandmother made many everyday quilts in the 1800's, piecing them on a treadle, quilting them by hand, using feedsacks and some left over clothing. They went under a pretty quilt and she would have been EMBARRASSED to have had them on display. They were made quickly for warmth, for utility. Every wife did this. The pretty ones were very, very pretty and you definitely never comfused the two. I don't think that the woman who made a utility quilt, if that is what you have, would want you to go to an effort t o save it. It has had it's life span.
