Make a captain hat out of paper if you're seeking an idea for your child's imaginative play or a project for a rainy day. Folding paper to make an image or shape is called origami, which is a Japanese art form. You can make the hat by folding the paper in various directions to create the shape, and decorate the hat using your favorite colors, beads, yarn and other decorative trinkets.
Lay half a sheet of newspaper on a flat surface. Alternatively, lay down a 8 1/2-by-11 sheet of paper.
Fold the paper in half vertically by bringing the top corners down to meet the bottom corners, and crease it across the top.
Fold both corners of the paper down to meet in the center, 1 inch from the bottom. Crease the edges of the paper to form a triangle.
Fold the front-bottom flap of the paper up to meet the triangle. Then, flip the paper over to repeat the process with the flap on the other side.
