Transformer Optimus Prime Costume

My 3 year old grandson, Layton said he wanted to be Optimus Prime the transformer, so I had to immediately start thinking how in the world I would do it. Well, I found some cardboard i had, looked for some pics of Optimus and got to work. I cut out pieces, hot glued things together and came up with the general design. I had to buy some white, blue and black spray paint, cheap stuff for a buck a can, found a mask at goodwill for $3 and a cheap pair of gloves to glue onto the front fenders. So about $8 all together. He loves it and can actually lay down to transform into semi!! Not too bad!
