Like someone else said, I either like the fabric, or I don't. Doesn't make a difference to me when it was manufactured. What matters is the quality of the fabric more than anything else.
I had a quilt top (8 point star) that my great grandmother made. She died in 1939, so you know the fabrics all predated that timeframe. She made the top for my Dad but he never had anyone to quilt it, because he was afraid to let it out of his hands. After he passed away, I had it hand quilted in both of their memories. At first I was worried about whether the fabric was still in good shape to bother with it. It was in great shape, so I guess she used good quality fabrics. I guess to whole point of all this is, quality not age.
