I buy whatever is on sale for 3 dollars a yard at several different web sites. So far I have not been dissapointed with my purchases.
I like Quilt in a Day because they have a large selection.
Hancocks of Paducah is good too.
For a complete line of fabrics I like Connecting Threads, all fabirc is less than 6 dollars a yard.
All the fabrics have been first quality.
I rarely go to a local quilt shop, they are too expensive. I live near a lot of them since I live in Phx. AZ. If I need something special I will go to one, its fun to look at all the fabric but the prices are all over 8 dollars a yard so just dont buy much. One shop is only 6.99 a yard so go there once in a while if I am over thier way.
