I'm with Bella Boo, I use and like too many to list. My very favorite is eQuilter, fast,excellant service, but mainly because of their web site, clear large pics, exact size of the fabrics' graphics. I've also had excellant quality & service from all e-bay shops that I've bought from.
Virginia Quilter;4my3Boyz;Connecting Threads;Fabric Depot; Hayloaft Fabrics; Marshall Dry Goods & the list goes on and on.
