I order on line from alot of different vendors. These are the stores I acutally go to and like alot
http://www.cityquilter.com I'm from NYC and they have great City fabric that I see nowhere else.
http://www.portsmouthfabric.com Portsmouth NH is too far away for me to go often, but guests always want to go for lobster and I go to the shop for fabric.
http://www.vermontquilting.com - huge selection, nice folks
http://www.quiltedthreads.com not cheap, but have a vast selection of gorgeous fabric and are truly nice people.
http://www.quiltaway.com has good sale fabric and a terrific batik selection, Carol is also a big Patrick Lose fan so I can get his old Playing with Marbles there usually.
Quilters Workshop on Main Street in Newport NH is my favorite - great people, great fabric and I can't find a website, although I know they have one.
I also love to shop at Usha Berlin's shop in Hudson, NY - Heirloom Batiks. She doesn't have a website, but does alot of shows. She's great and so are her fabrics.
