Redecorating?

I have been wondering something about this blog, namely the layout and appearance.  I have been using the same blogger template for over a year and wonder if it might be too boring.  I didn’t give it much thought when I chose it to begin with except to tweak some of the colors a bit, that part isn’t very noticeable actually.  And I do still like it, but I have seen several blogs with the same template.  That’s just too strange.  Should I change things up a bit?  Not sure where to start with that kind of thing.  Any feedback would be quite welcome on this matter.
