My son wanted to be a knight for Halloween - so instead of buying a plastic costume that would last one year I did some searching and found a cute idea for a handmade costume that turned out awesome. I bought a black t-shirt for a couple bucks at a craft store and cut out felt accents. I found a free pattern online for the helmet. This was the coolest part of the costume. We cut out the pattern in tag board and then covered it in duct tape for a metal look......pretty cool. Then I found some armor and a shield at a dollar store. Probably cost $10 including the long johns we bought to wear underneath (and now uses as PJ's).
