Folding Up a Dogi

Here is a step-by-step guide to folding a dogi.  Once it is folded, you can loop your belt around it, tie a knot and sling it over your shoulder.  It isn't such a common sight anymore, as everyone now uses bags, but could be employed in a pinch.

It should also be noted that the term "gi" as used for a karate uniform in English is not readily understood in Japan.  The correct term in Japanese is "dogi," though "karategi," "judogi" and "keikogi"  can also be used, depending on the martial art. 

Judogi date from the 1820s, while references to keikogi, often worn with a hakama, can be found in texts going back at least to the 1790s.
