Late Night Blog Beautification

So yea, here I am sitting here at 11:16pm playing with my blog, adding page elements, impressing even myself on my computer skills...but I still can't figure out how to make one of those pretty headers that others of you have. Someone help me please :) OH YEAH and become a "follower" of my blog, scroll down, on the left side (that's also something new I've magically added), much of this is "could I do it again? maybe, maybe not". Now it's 11:28pm, going to bed...
