When I asked; What do You Like About Blogger? several people commented on the lack of new templates made available for Blogger. If you're tired of having the same look as everyone else the best solution, at the moment, is to search the Internet for templates created by third parties. The best templates available are those that have been ported from WordPress.

Before you make any changes to your template back sure to backup and download your blog in case you should make any major mistakes. I'm just providing information here and can't be held responsible if something happens to your blog by using a third party template. If you need help with installation contact the developers. If you'd like to be able to make a simple changes to your template see the Table of Contents for a few tutorials.
