About 40 years ago I spent a hell of a lot of time and effort setting up a whole workshop that I shared with my father with walls of shadow boards for tools...........what a complete bloody waste of time that was.
Dad would never put anything back where it was meant to go, most of the time he'd just leave tools where they were last used, if somehow he'd manage to hang them on one of the walls it'd be on the first hook he'd find, nearly always on in the wrong place and usually on the wrong wall!
Around 12 years later we set up a new workshop, the old bugger wanted me to do shadow boards cos he said he could never find anything in the old workshop..........bugger that!
Poor ol' Dad is long gone now, and I still don't have shadow boards, but not for the same reasons, now I have so much stuff I couldn't possibly ever have enough wall space to hang it all from.
And now most of my work is at clients premises, so most everything needs to be in carry boxes and tool chests.
I couldn't even use the shadow foam set up in the tool chests as I have to jam that much stuff in them, I can't afford the space the foam would take up.
The poor ol' work ute has to carry so many tools it has to drag it's arse up the road like a terrier with worms!
