I Need a New Blog

Template, that is. I'm SO BORED with this one!!! However, I'm not particularly CSSS-savvy, so this is going to be quite a project. Basically, I want to make my OWN template, but I have no idea how to go about this. I've been looking online for "how-to's" on template designs, but with no luck! Grrrrrrr......any suggestions?? Is anyone good at making templates that would like to impart some of that knowledge with me??
