I've bought a lot (and actually used some...) of their fabric, and have used a lot of their thread, and really like it all. I have tons of their fabric that I got on clearance (usually half price), plus I usually had a coupon code for an additional discount.
One of the great things about their pricing is that when you get a fat quarter, you pay exactly 1/4 of the cost of the yard - unlike most places that charge you more per yard for pre-cuts. Same with strips, charms, layers, fat eighths, kits, samplers, you name it. Always the same price per yard, unless it's on sale. And their customer service is awesome.
Can't wait to try out their new stuff!
