I like to sew bags and found a Yahoo group that I recently joined. It's called sewing tote bags and purses. One of the blogs I found there through the posts is called Passion et Couture. The blog author has some great pics of bags she has made, especially her most recent bag called The Exchange Bag. Also on her site, she had a link to Pinterest where you can see all sorts of bags with links to where to find the patterns for some.
Here are some other bag resource links I have found:
