I worked at Hobby Lobby for a few years (moonlighting) in the fabrics department.
They carry a variety of fabrics including their own Hobby Lobby line of fabrics.
I've seen really nice quality...all the way down to average quality. I have always bought their fabric and used it in everything I make.
Their prices are reasonable, and the nice thing about Hobby Lobby is they have a 40% off coupon every other week or so.
And all their stores are closed on Sundays - the founder/owner believes that people working for him should be able to enjoy one day with their families.
