I use Bear Paw quilting a lot too. www.bearpawquilting.com. I love their service. The prices may be a bit higher for somethings, but they have their QQF or quality quilt fabrics for 20% off. I love blenders and use them as backings. They have a huge selection of blenders.
It's cheaper to buy University fabric through them, than here in town. I bought all my army fabric there and was very pleased with the cost and the quality of the fabric.
I've been curious about thousands of bolts and connecting threads though.
