This is a go board on a towel, written in fabric marker for larger pieces 2.4cm or less. Given some creativity you can find game pieces pretty much anywhere, be they coins, or stones of different types or colours or with sharpie markings to distinguish them.
I've been known for the use of towels for just about everything: bedding, a martial arts weapon, a climbing aid, clothing, bandages, packing material, the list goes on and on forever. Know where your towel is, at all times.
The other photos in this collection document the process.
