I made these for some of my students for graduation this year. They had to sign some paperwork before they could graduate and I made these for them to sign with. The hat is from the Wild Card cartridge. I cut it at 3 1/2" and folded it over the top of the pen cap. I glued them together and held them with paper clips until they dried. I got the pens at Walmart. I ended up making around 40 of them. Some of the kids thought they were dumb, but most of them thought they were an ok thing.
