Blog Remodel?

I am contemplating a little blog redo. I see so many creative ways to design a blog when I read though my google reader. I love the Japanese tape and vintage loveliness. Unfortunately, I am not knowledgeable about anything to do with web design. I also wonder is it even worth it. I mostly blog as an outlet for myself to share about my what happens in our crazy family. Should I venture on to the next level? I also have been wondering about starting a teaching blog. What do you think?

Here are some examples of cute blog headers....(I included their link so you can check them out too)
