The shop has to be clean and organized. I don't understand stores that have bolts four or five deep on the floor. Do they really think their customers enjoy bending down and pushing bolts out of the way so we can see what's behind them?
There is a nice LQS about 20 miles from my home. It has a variety of fabric and patterns. The staff is very friendly and helpful, and there have been times they provided water and cookies for their customers. I don't go there as often as I like because there are three other quilt stores within 6 miles of my home. Now that I think about it, I really should go to that other store to see what they have. Shopping there has always been a good experience.
