Rosa,
Sounds like you maybe found a good option with amazon. I was gonna suggest the Quilters Dream Washable Wool, but you definitely won't be finding that at Joann.
Wanted to add that in addition to the coupons you can find on the Joann website, you can also print or download to a smartphone Joann coupons from
http://www.retailmenot.com. Make sure to select the "in store" tab if you're using your smartphone. I never shop Joann without at least a 40% off coupon. Last week I had some 50% off coupons from the JAF website. So nice. My LQS's prices are WAY higher than Joann's, plus all the fabrics are Civil War reproductions with a dozen or so 30's reproductions thrown in there, so don't feel too badly that you don't have that option. There's no guarantee it would save you any money.
