Get paper

Place colored side down

Fold in half horizontally and vertically

Fold both diagonals

Fold all corners into the center

As if turning a page in a book, fold the large flap on the right to the left; repeat on reverse side

Fold the edges of the upper layer into the center

Turn paper over and repeat

Fold the top point down as far as it can go

Turn paper over and repeat

Voila! A Sanbo!
