I've made a couple of homemade Halloween costumes in the past, but didn't think I would this year as I moved to a new apartment in the summer (I like to start on Halloween early) and didn't really have a good costume idea anyway. I had seen the Geico Made of Money Man commercial many times before, but one day in September, it finally clicked with me that I could probably make it fairly quickly. So I bought a few packs of fake money and voila, it's been a success so far!
Step 1: Lots and Lots of Glue
At first, I was going to use a haz mat suit as the base, but realized that might not be easy to get out of when using the bathroom, so I changed it to a sweatshirt and sweat pants. Not only is it comfortable, but it's easy to put on and take off.
I purchased about 1000 bills of Motion Picture Money on eBay. I already had two hot glue guns, and bought a few packs of glue sticks and started gluing. I began with the shirt, starting at the bottom and working my way up. I decided to lay it out like a tile floor, but more random. I glued down a good base of bills, just to cover the shirt, then I added more bills, as needed, to fill in gaps.
Step 2: The Head
I used a head sleeve made for hunters and used the same concept--I started gluing bills at the bottom working my way up. I didn't worry about making the head look exactly like the costume since I was going to wear a motorcycle helmet. I used the part of the sleeve that can cover the mouth as the "beard." I folded each bill in halves and quarters, to make them smaller, and glued them to that part of the sleeves, tucking them over the fabric to create the beard.
