To strengthen the crease, run your finger down the fold 3-4 more times.
You should now have 2 creases along both centers (x-axis and y-axis) of the page.
Use the crease you made before to help line up the folds coming in from the corners.
The 2 folds should line up with each other.
The flaps closest to you should be folded in front of the back flaps, not over them. If you fold over the back flaps, you won’t be able to fold the back flaps themselves.
Crease the paper along its edges so that it stays in the square shape.
The bottom of the diamond should be the part of the paper with extra folds.
The bottom corners will line up to become the bottom point of a square diamond.
You may need to pull up the triangle inside the diamond while pulling apart the two sides. Try to keep the triangle inside the diamond sticking straight up as this will be your boat’s “mast. "
You can reinforce the corners with clear tape and tape around the bottom to keep your boat dry.
