I sketched out a quick pencil under-layer then started to ink it with a sharpie. However, I quickly switched to some sumo brush pens that I had. The sharpies weren't reacting well to the paper (the back of a glossy calendar) and the pencil lead for some reason.
I then cut out a bunch of noses out of construction paper and just left it black and white.
There were somewhere around 12 kids there, and it was a blast to see the kids having fun and lining up to play the game. It's certainly a good feeling to have kids enjoying something I made.
