Honestly, in doing the fabshophops, I do not like the stores that list their fabric by manufacturer where it is a grid with a white background and you have to go through way too many on the first page. Many are labelled by the name of the fabric line. I just don't like shopping that way. I prefer it broken down a bit more. Even Manufacturer and then line is better than scrolling through a gazillion pictures and names that don't make sense to what I am looking for.
I do like it split out into yardage, kits, fat quarters, pre-cuts, sale items, etc. And then themes are nice too!
eta: quite a few of them seem to use the same website template that just doesn't seem to work well for an online quilt shop. So I would say make sure your website works for what you are selling.....cheap/free templates might not!
