I used to go there regularly when I worked right around the corner. Of course, this was BEFORE I started quilting.
What are the brands of fabrics? If name brand, I think you can judge the quality from there. Look at the selvages rather than at the cardboard holders.
When I work in Quincy, I go over to Sewfisticated on Morrisey Boulevard in Dorchester. They are selling for 2.99 and 3.99 a yard. Most are name brand - some of the "lesser" brands in some cases - but I've found some of the same fabrics that are carried in my LQS. The key difference, I believe, is that the fabrics are not from older fabric lines.
The Sewfisticated in Framingham carries nicer quilting fabrics. There are three stores that are run by family members. Apparently, each has a different eye so, while they have some of everything, they concentrate on their "specialty".. The one who runs the Framingham store apparently has an "eye" for quilting cottons.
