As I mentioned in a previous post (website template design) Artisteer is a great way of creating a template without getting involved in the underlying code. Really it’s a clever template wizard rather than a template editor, but I’ve found it very easy to use and quick!
Artisteer is now on version 2.3 and you can use it to design templates for Blogger sites like this one. If you have a blogger site and want to change its template easily I suggest you give it a try. One feature I really like is its ability to automatically upload your created template directly to your blogger site. No manual uploading and fiddling with HTML and XML files required!
