I have a lot of their thread and I like it a lot. It is linty; in my experience all 100% cotton thread is linty, not sure if their's is any more than others. Like their batiks, I can't tell them from LQS batiks. I have quite a bit of their "mirage" fabric which I like the looks of but I've decided it is too heavy for anything but small pieces. Used for backing or borders it makes the quilt heavy. I have a quite a few of their solids as well, which are fine.
A lot of their fabric designs don't do much for me, so I don't purchase many of the prints.
Never had a problem with customer service, but then I don't think I've ever had a problem that required customer service.
