Abstract

A method of forming an origami envelope from a sheet of material is provided. The method comprises folding the sheet of material to create at least five fold lines. The origami envelope is formed from the sheet of material comprising at least five steps. In some embodiments, the method comprises an optional folding step. The optional folding step includes folding the sheet width wise to create an optional crease line.

Dependent claims

A method of forming an origami envelope comprising:

providing a sheet of material having a top right corner, a top left corner, a bottom right corner, and a bottom left corner, a top edge extending between the top right corner and the top left corner, a bottom edge opposite of the top edge, extending between the bottom right corner and the bottom left corner, and a first and second side extending between the top and bottom edges, the first side extending between the top left corner and the bottom left corner, and the second side opposite of the first side, extending between the top right corner and the bottom right corner;
orienting the sheet of material such that the top and bottom edges extend width wise, and the first and second sides extend length wise;
folding the sheet of material to create at least five fold lines, the at least five fold lines comprises:
a first fold line extending diagonally between a first midpoint positioned at one of the first and second sides and a first point positioned at one of the top and bottom edges;
a second fold line extending diagonally between the first midpoint and a second point positioned at the edge that is opposite of the edge having the first point;
a third fold line extending diagonally between a second midpoint positioned at a side opposite to the first midpoint and a third point positioned adjacent to one of the first and second points;
a fourth fold line extending diagonally between one of the top corners and a fourth point positioned adjacent to the second midpoint;
and
a fifth fold line extending diagonally between the first or second point that is positioned at the top edge and a fifth point positioned adjacent to the second midpoint, wherein the second midpoint is positioned between the fifth point and the fourth point, and
folding the sheet of material to form the origami envelope comprising at least five steps, wherein the at least five steps comprising:
a first step of folding the sheet of material along the first fold line to create a first substantially triangular structure;
a second step of folding the sheet of material along the second fold line to create a second substantially triangular structure;
a third step of folding the sheet of material along the third fold line to create a quadrilateral structure;
a fourth step of folding the sheet of material along the fourth fold line to create a top and a bottom layer and a third substantially triangular structure extending from the top layer;
and
a fifth step of folding the sheet of material along the fifth fold line to extend the third substantially triangular structure from the top layer over to the bottom layer.
