I've noticed that a lot of people who visit this blog are looking for new Blogger backgrounds and layouts. I'm always on the lookout, too - even when I find one I really like, you never know if an even better one is out there somewhere waiting for me.
I just recently found a new site full of great looking Blogger templates, so of course I had to share. It's called Simply Fabulous Blogger Templates, and I haven't looked at all of them, but the templates I've seen are really nice. There are also some nice tutorials to help you change your template, add and configure your widgets, and add custom text to your header.
