Cut long strips from white, green and orange magazine pages, about 1" wide.
Take one of the orange strips and roll it up in to a little cylinder. Glue it down at the end.
Make 3 of these and stick them together.
Take a white strip and wrap it around the 3 cylinders. Continue round and round, gluing on new white strips, until the sushi becomes a nice size.
When you're happy with the size of the sushi. Take a green strip and wrap it around, gluing in place.
I made a couple of tiny sushi rolls and turned them in to earrings.
