Ok, so there's not only a couple of us that feel the same about Quilt Hut lol
Calico Cat is a nice little store. Very nice and helpful people there.
I've never had problems with Fabric Mart's fabric. Maybe the "bad" fabric just jumps out to you. lol
I didn't make it into Kuni Island in January when I was there. Meant to go over there, but just ran out of time. <sigh>
There used to be a place on Moanaloa Rd that had fabric and you could also rent their longarm. It was in the shopping center across from the McDonalds near the library.
