I did a quick search but didn't see that anyone had posted this link, on Checker Distributors' website. It has a whole bunch of patterns for quilts, and if you click on the text links in the "newest patterns" box you can find lots more. The collections used in the quilts are often older ones, so in most cases you'll have to use your creativity to find other similar fabrics to get the same effects.
