The constrictor knot is appropriate for situations where secure temporary or semi-permanent binding is needed. Made with [[small-stuff]] it is especially effective, as the binding force is concentrated over a smaller area. When tying over soft material such as the neck of a bag, take care to keep the wraps of the knot together.
