Making a collage is easy, if you have the right materials. You will need to start with a basic idea of what you want your collage to look like, a theme. Then, you will need to collect pictures or tiny trinkets that support the theme or idea. Arrange them onto your poster board, or whatever you have chosen as your background. Keep arranging until you find a look that appeals to you. When you have gotten that special look, it is time to glue things down. And, voila, you have your collage!
