There are also some designs where the whole box is folded from a single sheet of paper. This is one those:
The Cat Face Box is a fun model, that can be found in Tomoko Fuse's book, Origami Boxes from a Single Sheet, ISBN 4480872035 (in Japanese).
I like this design because, unlike most of the others, it has an irregular shape. The box resembles a cat face, although because of the pattern of the paper, mine looks more like a leopard.
The box is folded from a rectangle with 1:√2 proportion ("A" proportion or silver rectangle) that I cut from a 12" (300 mm) square of scrapbook paper.
