this is a good costume of a jaffa serpent guard from stargate sg1 made out of card board. there are 4 parts: the helmet, the chest plate, the belt, and the shin guards.
Step 1: Materials
for this build you will need card board preferably double corrugated, a hot glue gun (cation hot, don't touch the metal pointy end it will burn you, it hurts), spray paint, (i used gold, silver, bronze, and dark green), and you will need a good sharp box knife
optional - dremle, 2 red led's, and 2 watch batteries
