Plain Jane....ugh!

I have GOT to do something about that plain, dreary, boring, blank white box above on the top of this page. Now...how do I go about figuring out how to add something in there? Creating artwork for that is a piece of cake. But where exactly in my template do I put it - or is that even how I do it? I've scoured blogger and can't seem to figure it out. Do you know? Post a comment and let me know if you do. That white box is driving me crazy!
