Costume builder Shawn Thorsson, whose work we've featured previously on Kotaku, has been filmed by Maker Faire TV in an episode devoted to explaining how some impressive tools and a lot of elbow grease can bring video game characters to life.
Specialising in Halo gear, Thorsson's advice is of more help to anyone wondering how armour or other static pieces of equipment are, or can be, made. He's not going to tell you how to sew a cape on or stitch a garter together. So if your ideal costume is Master Chief in a maid's outfit, he'll only get you halfway there. Sorry.
