A method of constructing an origami-style of foldable picture frame is described. Firstly, a unitary blank of sheet material is cut to a described shape. Secondly, a series of cut lines necessary to form a picture viewing window are placed on the unitary blank. Thirdly, trim off corners enabling opposed edges of a portion of the unitary blank to inserted into the picture viewing window. Fourthly, place a series of fold lines are placed on a portion of the unitary blank to form a primary panel. Fifthly, a series of fold lines are placed on a portion of the unitary blank to form a secondary panel adapted to overlay the primary panel. Sixthly, a series of fold lines are placed adjacent the cut lines where the picture viewing window is to be positioned. Seventhly, a series of fold lines are placed on a foldable portion adapted to be inserted into the picture viewing window. Eighthly, a series of fold lines are placed on another foldable portion adapted to be inserted into the picture viewing window. Ninthly, the unitary blank of sheet material is folded along the described fold lines to form a picture frame.
