1. Start with a letter size paper. Fold the paper in half crosswise and crease, then unfold.

2.  Use a ruler to draw folding line A as shown in figure. Repeat fold and unfold using valley fold and mountain fold. Push the right corner to make an inside reverse fold.

3. Draw folding lines A and fold and unfold along line A. Crease line B by bringing top edge C to line A. Crease B line and unfold.

4. Push the right side corner for an inside reverse fold.

5.  Fold the top right side layer to left and fold the second left side layer to right. Then turn the paper over.
