Hi Karla,
They are wonderful quilts. I restore quilts and have a passion for old quilts and old fabrics, however, some of yours look like they just need to be left alone and cherished as is.
I would display them so I could enjoy them! If you ever decide to try to restore them be sure to get fabrics from the period in which they were made, otherwise you would spoil their beauty. I agree that that the wear reveals a unique character to them. And yes, some dyes years ago were harsh and ruined certain fabrics, also some fabrics were stronger than others.
So glad they were given to you :D
