Tridecagon, also known as the triskaidecagon, is a 13-sided polygon. There are several origami methods already available for folding the tridecagon but the simplicity of my approach may be of interest to people. You may use the tridecagon to transpose origami designs based on other regular polygons.
This is my first convention as a guest of honor. With around 35 guests, placed in the heart of Krakow, the convention is like a family-gathering. The organizers, the Burczyks, focused the convention on the topic "Origami is Art."
