Pam, What a wonderful find. If those are not vintage fabrics they could be some of the new reproductions. You are so lucky to find such treasures. My grandmother lived in Illinois. I am in Maryland and was not able to be there when her things were sorted and distributed. I have a few things that she sent me when my mother visited her at different times. I also have a flannel quilt she made for my daughter when she was born. My mother was her only daughter. Two of my uncles lived in her town and looked after her. Neither of their wives were interested in sewing or quilting so they probably disposed of anything like that, unfortuneately.
I hope the quilts bring you fond memories and comfort for years to come.
