I think that Santee is the only company that still prints fabric in the US. But... their prints aren't very special, only a couple of screens/colors so they can be produced for less cost. Santee is one of the many companies that supplies JoAnn Fabrics (many of the "basics" on their calico wall, $3.99 - $4.99 price point).
However... to the best of my knowledge, the greige goods (raw fabric) are all from Pakistan or India. I don't think any of this is US-made.
