I have been going through my stash prior to moving and I have to say a lot of the fabrics from back in the 80's and 90's were great quality. Some of them seem to be artificially stiff and they mostly seem to be dark green. Don't know why. But most of them are great, maybe it is just that the quilters who gave me their scraps, bought good quality fabric.
Most of my scraps are so "vintage" that they are "Made in USA".
When I started quilting, it was either hand quilting or tying. I did hand quilting so I was able to offer something different from most of the quilts that were sold in Vermont. Then the imported quilts came in and had a big impact on the market.
