This quick tutorial video shows you how to tie your karate belt.
Note, that belts and uniforms are not required to study any of the CMATOS material. If you are attending a dojo or other formalized training, you may be required to wear a uniform and provide identification of your rank through the belt you are wearing. For in person lessons and training at your dojo, please speak with your instructor for proper etiquette.
In the CMATOS system, the only person in the room who wears their belt with the knot in the center is the current instructor who is teaching. Everyone else should wear their knots to the side to indicate respect for the rank. This becomes particularly important when having multiple black belts in the same class so that students can easily identify who their current instructor for that lesson section is.
