Things You'll Need
One poster board
Pencil or pen
Coffee can or bowl
Hot glue gun
Dress the part of a boxer, complete with your own championship belt. This boxing belt is a pretend belt that can be worn as a Halloween costume or for a school play or function. Customize the size of the belt to fit the waist of the wearer. Complete the outfit by wearing shorts, socks, sneakers and a robe.
Measure and draw a rectangle on a piece of poster board using a ruler and a pen or pencil. For a child's boxing belt, the rectangle should be about 6 inches wide by 18 inches long. An adult belt should be bigger with measurements of 8 inches wide by 20 inches long. Curve the edges of the rectangle by tracing a half circle using either a coffee can or a bowl.
Trace a circle on the part of the poster board not already used. Use your coffee can or bowl to draw a perfect circle.
Cut out the curved rectangle and the circle from the poster board. Set aside the remaining scraps of poster board.
Cut a piece of foil big enough to cover one side of the circle completely. Wrap the foil around the front of the circle and tape the remaining foil on the back side. The back side will not be visible.
Decorate the front of the circle using permanent marker. Write "Champ," "Boxing Champ" or "Champion" across the front in the center of the foil.
Cut a vertical slit the width of the belt on both the right and left sides of the belt, next to the curved edge. Both slits should be about 2 inches from the end.
Weave one end of the belt through one slit and through the other end of the poster board. When done, the belt will be on the inside of the poster board and the belt's buckle will be fastened against your back.
Glue the circle onto the front-center of the boxing belt using a hot glue gun. Press down firmly and let the glue dry before wearing the belt.
