1. For the arrowhead, cut three equilateral triangles from the blue felt, about 2 inches per side. For the tail feathers, cut one right triangle from each of the three remaining felt colors, with long sides of about 2 inches and short sides of 3⁄4 inch.
2. Cut the chopstick into two equal halves.
3. Glue the blue equilateral triangles evenly around the tip of the pointed half of the chopstick, applying a line of glue down the center of each triangle. Make sure the top point of each triangle lines up with the point of the stick. Then glue the edges of the three triangles together to create a three-dimensional arrowhead.
4. Fringe each tail feather along the hypotenuse. Leave at least 1⁄8 inch intact.
5. Apply a thin line of glue along the three long edges of the tail feathers, opposite the fringing, and glue them evenly around one end of the other half-chopstick.
6. While the glue is drying, further secure the tail feathers to the stick by tying a 3-inch piece of thread around them, making sure it goes between the fringe, and tying a knot. Trim the ends of the thread. (This process is similar to the traditional method of arrow making, called fletching.)
7. Glue the undecorated ends of the chopstick to either side of the headband, making sure they form a straight line across when worn.
