1. With a box cutter or sharp scissors, cut the boxes down to size. The biggest box wasn't cut down. Only the flaps were cut off.
2. Using paper-safe glue or double-sided adhesive, cover each box with coordinating scrapbook paper, almost as though you were wrapping a present. In order to make the tops look finished, clip the corners in a "V" formation, fold the flaps over, and secure the flaps with masking tape or Japanese craft tape.
3. Line the boxes up in descending order. Using ample amounts of paper-safe glue or double-sided adhesive, adhere each box to the other.
4. To secure boxes, tape the bottom with long pieces of masking tape.
VARIATION: Use a differently-shaped box for a paper and card organizer.
