3-strand lanyard knot

[osteoderm]

If you really have time on your hands, how about an 8-strand square sennet crowned with a little star knot? Seriously, there are about a zillion sennets using anywhere from 3 to 1266474 or so lines... Check Ashley's, or The Marlinespike Sailor.
i got carried away one season and made little sennet pulls for every shackle, gate, and PFD zipper-tab on a boat i once worked on.
