I say do it! If you have that much high quality fabric in your stash, and an inclination to buy more, now seems a good time to sell some of the older choices. You might consider offering one or two choices. I like the idea of flat rate boxes but the postage alone on that would be over $10, plus the price of the fabric. You could offer a 1 lb. envelope for a lower price. Anyway, good idea and I would be your first customer as I love LQS quality surprises!
