Screw organizing
Another use for the jars, and this one gets them off the worktop entirely.
Still on the subject of jars, a day after the last lot. This is the other thing worth doing with them, and it is the one that finally cleared the workshop bench.
We got through a great deal of peanut butter in this house: one of us at breakfast, one of us more or less nocturnally, and me on the strength of a 1970s habit I have never grown out of. For years it came in plastic jars, and the plastic ones went out to the garage instead of into the recycling. They are now glass, which is nicer to eat out of and no use at all for this.
The whole of it
The lids screw to the underside of the wooden shelf above the work top. Fill the jar with whatever small thing needs a home, and twist it up onto its own mounted lid.
That is the entire method. There is no step two.
What it gets you is small-parts storage that hangs in space nobody was using, at eye level, transparent, and impossible to knock over, because the jar is only ever off the shelf when it is in your hand. Screws in one, picture hooks in another, the washers that otherwise migrate to the bottom of a drawer for a decade.
Two things learned the slightly harder way. Put the screws through the lid near the rim rather than dead centre, or the jar wobbles as it tightens. And leave enough room between lids that a hand can get round a jar to turn it: a row spaced for the jars is a row you cannot use once they are full.
