Awww, I think I could teach you. Start by trying to look at the tip of your nose. Once your vision does sort of a double vision you've done it. If you've ever seen a Magic Eye picture, the sensation is similar to that. Once you get a feel for it shift your view from the tip of your nose, while crossed, up the bridge of your nose, once you get to where your bridge meets your brow, you've got it! ^_-
