Hancocks and Ben Franklins were my "go to" stores for fabric (both a 10 min. drive for me). They closed a couple years ago in my area. I could always find something that inspired me in both of these stores and the fabrics I purchased where good quality. (When I shop for fabric, I like to buy everything I need to make the quilt including the backing.) I shopped Mary Jo's (1 hr away) when I needed 20 different fabrics for a Bargello ... but from reviews I've read recently, I don't think they carry much quilting fabric any more.
So I'm left with Hobby Lobby & Walmart (less than 10 min. drive), 1 LQS (15-20 min. drive) and JoAnns (40-45 min drive). To be honest, I'm not thrilled with any of them. I stroll through the fabrics and, if I see a fabric that really inspires me, I can't find coordinating fabrics I like. I may try ordering some fabric online but I really prefer to feel the fabric ... and trying to coordinate colors can be a little tricky as I don't think colors on the computer always show true.
I try to always buy a good quality fabric even for my donation quilts but I do have to watch prices. Since I try to cooridnate all the fabric I need for a quilt in the store, they are usually of comparable quality.
