Origami Box (A4 Paper, Not Square Paper) » OrigamiTree.com
In this tutorial, I'll show you how to make a paper box (origami box) out of one sheet of A4 paper (8.5" x 11"). This is a great paper craft for those who do not have origami paper lying around because you can use regular computer paper, and not have to worry about cutting it into a square sheet.
