These tiny boxes are made out of wallpaper samples. They measure approximately 3, 4 and 5cm square. The design is from Origami Boxes by Tomoko Fuse. Four square sheets of paper are required to make each box, two for the top and two for the bottom. This type of folding is also known as unit or modular origami. No scissors, glue or tape used! I think they would make fabulous ring boxes!
