My son’s Homemade Boy’s Knight Costume is made with cardboard. The only things we purchased were the yellow ostrich feather and the silver mesh cloth for the chain mail underlayer. The rivets of the armor are just dots of hot glue painted with silver spray paint and then a light patina was washed on with thinned black acrylic paint that is then rubbed off the high points. It was so windy the plume of his helmet was difficult to photograph.
While this knight costume stands alone, his sister was a Medieval Lady.
