The simple chain sinnet is the chain sinnet most often
used in the world of knot tying. In addition to being

decorative, it also serves, when tied loosely, as a method of
packing short pieces of cord or rope in a manner that

prevents tangling, a useful device for campers, climbers,
and boaters. This method allows the cord or rope to be

untied from the chain with ease. Once tied, the cord
assumes an interesting elasticity.
