They do really good storage units that are useful for quilting. I have also bought fabric from there for backing, and they also do a 100% cotton thread, but limited in colours.
Other than that I hate the place. I cannot do with having to walk through the whole store when you know the thing you want is at the final department, and there is no short cut. I have also never been able to find a car space near the entrance. Don't go there unless I am desperate.
