A bloody knuckle knot is the result of a row of half hitches fused with a blood knot--this video teaches you how to tie one. Make two loops with your rope then loop them over your thumb. Take the tail of the rope and keep making loops and adding them to the others on your thumb, to produce a row of loops. When you have five loops, slide them off your thumb, take the end of the rope and pass it through the loops. Pull out the slack but do not tighten, then take the other tail and pass it through the loops the other way. Gently tighten, adjusting each loop so it is even. Follow this video to make an interesting and unusual knot that can be worn as a necklace.
