Here I've decided to integrate my existing profile picture to the timeline cover photo to give it a unique minimalist-seamless look. I'm really diggin' it for now.
What about you? Any bright ideas for your cover page? Tip, set your cover page dimensions to 851(L) x 315(H) pixels so you end up with a nice crisp image. If you let facebook do the resizing for you, chances are you'll end up with a blurred crappy version of your original picture.
