It's amazing what you can do with a gel pen. One of my current favorite looks is actually one that's extremely easy to create: Use a gel pen to create a border around photos. It's easy, but very effective.

You can us a white gel pen or opaque marker to create a border around photos in many different patterns. On the photos above, I experimented with heart and swirl patterns. On the layout below, Suzy Plantamura used a dot-dot-dot-line pattern to highlight all her photos. Try using multiple designs to create the look you want.
