To tie your karate belt tightly and efficiently you only need to follow a few simple steps. First, find the center of the belt; do this by putting the two ends together. Put the center on your belly button, and wrap completely around yourself, now finding the two ends in front of you. Bring the left end over the right, and grab both pieces with your left hand. Now tuck the left end under. From there, place the right side over the left. Now take the bottom flap and wrap it around the right piece and stick it through the hole. This will create a square knot. Don't just pull it; tightly snap it out a few time. This will create your tight knot.
