They are sort of the official "archive" for Hoffman batiks, especially the older ones.
They might charge more for that 8 year old discontinued mottled batik that you have to have to finish your project, but they're the only ones that will have it. Their site is better than Hoffman's when it comes to tracking down fabrics.
Also, they have EVERY batik listed, so you can see if a pattern you like comes in other colorways or, conversely, which patterns are available in a specific colorway.
Love them!
