I agree, nice job. What looks also very nice if applied properly, is the flat lacing cord that is mentioned above for aircraft wiring harnesses. It is a polyester cord and comes in two types (and black or white). One is a "dry" cord and feels dry to the touch and is difficult to make neat bundles with. The other is a waxed cord and feels waxy to the touch and sticks to itself and perhaps the wire bundle just enough to make it way easier to tie off. Normally it is not applied with a continuous strand, but just individual knots with the ends snipped. With the waxed cord you can start off with a "double half-hitch" pull it tight and it will stay until you tie it off with a square knot or overhand "granny knot". It is also the same as rib stitching cord that is used to attach fabric aircraft covering to the ribs of a wing. Rib stitch cord also comes in round or flat braid but almost nobody uses the round cord because it shows too much under the fabric tapes applied over it on aircraft. A spool is not that expensive and will last you lifetime if you are not stitching aircraft wings but just tieing off wire harnesses on your hobby cars.
