Here's the website for S R Harris:

It's a cut-your-own place. All fabrics are 50% of the posted price in the warehouse (but those prices are sometimes a little inflated, so don't get expectations *too* high). Plus, be sure to check the coupons for the month on the website before you go. Last time I went their batiks were on sale, and I think I paid $7/yard (most were Timeless Treasures). They also had quite a selection of extra-wide batiks for backings that were a very good deal.
The warehouse is huge. Put what you want in a cart, go to a cutting table, and measure and cut your yardages. You write the amount and price per yard on a small red sticker that you place on each fabric cut. Anything 5 yards or over, and anything silk, you are supposed to get an attendant to measure and cut for you.
They have everything you could think of in this warehouse; it's not just cottons.
