2-hole punch, makes a great journal cover. Students will bring a box from home, as in their favorite cereal, etc. to make things more personal. The inside will be 9" x 12" drawing paper cut in half and hole punched, and the rings are the 1.75" school-variety that students may open up themselves. I love that this is recycled, inexpensive, flexible, personal, and something that I think students will take pride in building until it is thick with art and art studies.
