Step 1: Start with a rectangular sheet of craft paper. If the paper has a colored side, make sure it is facing down.

Step 2: Fold the paper in half horizontally to create a crease in the center of the paper.

Step 3: Fold the paper in half vertically to create another crease in the center.

Step 4: Bring the right edge of the paper towards the center crease line, folding it diagonally to create a triangle shape. Crease the fold well.

Step 5: Repeat the previous step for the other edge of the paper, folding it diagonally to create another triangle shape. Crease the fold well.

Step 6: Fold the bottom edge of the paper up to the bottom of the diagonal creases you made in in the last two steps.

Step 7: Flip it over.

Step 8: Repeat the step and fold the bottom edge.

Step 9: Open the gap of the folded triangular-shaped origami pieces.

Step 10: Bring the top corners of the paper down towards the center of the paper, folding them along the diagonal creases on two sides.

Step 11: This will create a diamond shape.

Step 12: Fold the top layer of the bottom point of the paper up along the top edge of the paper to create a triangle shape.

Step 13: Flip it over.

Step 14: Repeat the process. It will create a triangle shape.

Step 15: Similar to step 9 open the gap in the middle.

Step 16: Fold it along the two creases on to sides to create a diamond shape.

Step 17: Gently pull the two sides of the boat apart to create a small opening.

Step 18: Pinch the bottom corners of the boat and pull them down slightly to make the boat more stable.

Step 19: To make the flags cut out triangular colorful craft paper and a thin strip from cardstock paper.

Your origami boat is now complete! You can now use it as a decoration or float it in water.
