I like www.quilterscache.com. The only thing that is a bit tough is estimating fabric as she only shows you how to cut out for one square.
I have also found that I am pretty good at being able to replicate a lot of what I see. And in calculating how much fabric is needed.
That said, what i do is if I see a quilt out here that I really like, I try to copy the picture and the name of the pattern and email it to myself at a gmail account. So now I have access to the information in the future.
Also if you do the FabShopHop online, you can check each site for patterns. If you find a designer that you like, google the name. Many have sites of their own.
Also check out the fabric manufacturers sites. Often they have free patterns (RJR, Moda, etc)
