This is made with 17.5 x 17.5 cm chiyogami and pop chiyogami, which are larger than standard (15 x 15 cm) origami paper, so bills fit easily. (Bills are not included. They are for illustrative purposes.) Please see photos 3 and 4 for the finished size. (Photo 2 compares it to a standard size. A small envelope made with standard size paper is also included.) Thank you very much. Thank you for looking.
