mainly their prices used to be lower because THEY own the pattern/designs and used to have it printed themselves. Now that it is farmed overseas (like all else) the prices are about the same, but the quality is really less than what it was a few years back.
THe last black batik I got from them was so sheer, I had to put muslin behind it to give it body!
THeir Mirage line used to be good too, but again, very thin now, and not really dyed through like it used to. It is very WHITE on the back of the fabric.
