1. A coloured picture, photograph or image related to your special event. You could cut a picture out of a magazine, or use a photograph, or even draw a special picture yourself.
2. A coloured sheet of cardboard that's bigger than the picture you're going to use.
3. Some coloured sheets of paper, about A4 size. It's better if you can have some sheets that are different colours.
4. A pair of scissors and some paper glue (such as Copydex).
