Classic car influenced cable clip

Wiring up Clayhanger Yard, I've used a trick to keep things neat that I picked up from a classic car magazine.

Cable clips are supplied with what I think are masonry nails. You hold them in place, whack the head and your wiring is firmly fixed to the wall. If you want to use them in a car, and who doesn't aspire to neat wiring in their classic, whanging nails into the metalwork doesn't work.

The trick is to replace the nails with small screws. Self-tappers for a car, brass for woodwork. I've binned the nails as bashing them into the baseboard seemed a bit violent. Screws seemed gentler and less likely to disturb anything.
