I live about an hour from Hamels. Their shop has so many fabulous fabrics that it is very dangerous to the bank account so I don't go that often. They also have super stitcher weekends the first weekend of the month when all fabric from the bolt is on sale. I am quite certain on-line sales qualify. Weird, I haven't received my email about that yet this week. Must be coming tomorrow.
Wineberry Fabrics is no longer a brick and mortar store. Sometime in February they are launching an on-line store. They had some really nice fabrics when they were brick and mortar.

Along Came Quilting is a great store with which to deal online. She is super helpful. The first time I dealt with her she phoned me long distance because she had the fabric I wanted but not all in one piece and she was concerned I would be disappointed.
The only dealing I have had with Sew Sisters is when I emailed them with a question and no one got back to me.
There is also A Great Notion. They have almost every notion and gadget you can think of.
