the belt is the easiest part of the costume. but this does not make it unimportant. it keeps your chest guard tight to your body.
first cut a strip of card board about 3 inches thick make sure in fits all the way around your waste with enough space to over lap
then cut out the shape of the belt buckle. the shape is in picture 2. then cut thin strips of cardboard out and glue them on as in picture 3.
the next step it to install the rubber band. just put it down put lots of glue on and around it and stick piece of cardboard on top. this is in picture 4
the last step of the belt is the hook. this is the most important part of the belt because it changes the belt from a piece of cardboard to an actual belt. to make the hook you take some thing round and wooden, i used a bamboo skewer, and stick it through the cardboard at an angle so that the rubber band cant come off. like in picture 5. use lots of hot glue on both sides like on pictures 5 and 6
the rubber band should hook around the hook like in picture 7.
