Collage has been an art form since it was first seen in the works of Pablo Picasso. It gives you an opportunity to be completely free and creative. There really are no rules here at all. Just add little bits of whatever you like that are acid-free, lignin-free, and that will not gouge or cut treasures on the opposite page of your scrapbook. Collage gives you a great opportunity to retrieve old jewelry or little tidbits of your life from the junk drawer (that we all have) and create a page that will be near and dear to your heart and to the hearts of your posterity. You can do an entire page or just a piece like a frame, tag, or title. When it comes to collage Picasso has no more skill than you have so just go for it and have a great time.
