| Spot ties are used to tie
leads together in a cable for neatness.
It is useful to make the wires different colours to facilitate tracing of leads. Special lacing cord is available. It has a nylon centre which makes it difficult to break. Start by making a clove hitch as shown below. |

| Pull the knot tight so that
it cannot slip along the cable.
Then do an overhand knot on top (half a reef knot). I'd draw a picture but I'm too tired. If you are desperate ask a boy scout. Space the knots about the
same distance as the diameter as the cable but no closer than 10mm.
