I like crowsnestquilting fabrics, too - she's really good and I bought a boatload of "In Full Bloom" when she had the full line in stock.
My favorite fabric seller is Judipat at Quilt Unique - no more than $10.50 shipping on any order and she carries a huge variety of wide backing fabrics including modern and antique prints, solids, batiks and tie-dyed at *really* low prices.
If you do a lot of quilts to give to Project Linus or QOV and such, she has a lot of bargain flat folds. Very fast and reliable - eBay like it used to be. :)
