Their fabric isn't a poor quality, but some of it is harsh feeling kind of like the dye has been painted on. If it's not fairly pliable and soft to begin with, it hasn't gotten any better after I washed it. Having said that, at a price of somewhere around 5 to 9 dollars, I buy fabric there all the time and no one has complained about the quilts I make with the fabric. I really like batiks and wish they carried more of them.
I don't mix actual quilt shop quality fabric with the Hobby Lobby fabric in a quilt. That is when you can begin to tell the difference with some of their fabrics.
