If you don't already have a copy (and maybe if you do!), David Brown Book Co. has this lovely book on sale for $7.98!!! Retail price is $33.95. You must use discount code 492-12 at checkout.
(I love this book. I'm very seriously considering buying a second copy!)
ETA: I found this sale in their paper catalog, so you might have to call them. It was listed in the "Textiles -- Bargains" section.
