Some uses of Washi are stumbled upon in times of need. They are no less valid. If you find yourself on a Christmas market, pedaling your wares in near freezing temperatures, and you get your down filled coat caught on a rough edge of box steel, fear not. Washi will effectively tape up the hole, preventing you looking like you've been plucking a pekin duck.
It will not, however, prevent you from being looked at like a hobo.
