1. Make your folder with corrugated cardboard: two large pieces the same size and a spine. Bind them together with artist tape. The tape should be flexible so the folder can bend.2. Choose your paper. You will need two sheets of paper that are wider than the height of your folder and one very large sheet of paper appr. double the size of your folder.
3. Glue your smaller sheets of paper onto right and left hand pieces of your folder. They should cover 1/2- to 1/3 of the cardboard with a generous overhang. The over hand is very important, there should be at least an inch of paper overhanging the cardboard.
4. Flip your folder over. You should see the underside of that overhung paper. At each corner, cut a notch. The notch should line up with the edge of the cardboard.
5. Fold the corners of the notch into the triangular shape seen in the photo. Glue the triangles down. Repeat for all 4 corners.
6. Fold the flaps (with the glued down corners) over the pieces of cardboard. Glue flaps down.
6. Repeat on other side. So far, your folder should look like this.
7. Flip your folder over. Take your large sheet of paper and cut it to a size that covers all the exposed cardboard with at least an inch of overhang on each side. You want it to overlap the other paper.
8. Glue paper down. The paper should overlap the already glued paper and overhang off the boards.
9. Flip folder over. Fold over hanging paper over and glue. It should look like this.
10. Take the remaining paper and cut it so it is about 1/2 smaller on all sides than your folder. It should be large enough to cover all exposed cardboard and overlap the glued paper--but it should NOT overhang.
11. Glue the paper down, so it looks like this. While the glue is still moist, fold up the sides of the folder so that the spine does not get stiff in the wrong position.
12. Ta-Dah! You have a folder. Now make some art to go in it.
