That is the thing about old utilitarian quilts the fabric often was from different eras. It kind of looks like there are some sixties and some fifties in there. But because many of the fabrics are kind of timeless. Who knows?
It is a nice old quilt and you are lucky to have it. Bless her heart, she sure was a frugal woman. You gotta love that! ps... Paisleys have been around for ages!
Edited to say ... I Love that roaring fire in the picture. It looks so homey.
