I'm sorry you've had poor experience with their fq's. I recently bought six coordinating fabrics from there, and am very pleased with them. I'm making two beautiful blue, brown and cream quilts for Christmas gifts. The fabric tends to be on the 'thin' side compared with lqs quality fabrics, but with a little Best Press, I'm able to get them to 'thicken up' a bit more before I cut and sew.
I'm not ruling this store out, completely. I think that you can still find some decent fabric, there. The novelty fabrics by Heidi Grace are rather nice. I don't care much for the Debbie Mumm fabrics, but like I said, there are still some fabrics (not the fat quarters) that I would make stuff with.
