We had a store called Adrian's in the town where I grew up in Mass. All kinds of fabrics. I also remember getting fabric at Zayre's (like a K-mart).
When I was in college there was a fabric store that was all overstock, etc. It was a mess but if you could find what you wanted the price was right. They specialized in seconds of Vera fabric and linens (the ones with the big flowers). This was back in the 1970's.
