My son was in a Halloween parade with his Cub Scout pack and they were to dress up as something from a specific part of the US. Our den had “North East” and since my son is a huge coin collector we figured that a New York state Quarter Coin Costume would be perfect (and of course the Philadelphia mint is in the North East as well).
I found some high res images of quarters online and set my printer to print them at a huge size (it staggered the image onto several sheets of paper). I then put it together like a puzzle and taped it onto a big round piece of cardboard. I then covered the whole thing in clear shelf liner paper and attached the two halves with clear packing tape (two pieces put together – both sticky sides together to make a strap.)
Everyone loved it!
