Can anyone recommend a good webpage or guide to espalier? When we bought our house, it came with a winter blooming espalier camelia that is well established, but quite overgrown. I never learned how to prune or train espalier in my hort classes. Most websites only have a text description, and I learn better visually. I'm assuming it should have a flat look to it when finished.

Here are a couple of shots of the current look:
