A trout net on deep clearance from Orvis now holds fruit up and off the pantry counter (and cooled in winter by the courtyard's hopelessly drafty window).
A dab of sticky-putty un-damagingly holds a cheap clothespin to the cabinets in the kitchen (intended as temporary... but still there) to hold grocery lists, printed recipes, etc.
An oversized $5 ladle from a restaurant supply store in Chinatown holds up to $40 worth of spare change.
An old deep-sea lure with the hooks filed dull now holds keys.
A restaurant's slotted spoon is bent into a "Z" and keeps pot-scrubbers high and dry near kitchen sinks.
12 cheap darts are used to hold olives into a (10 ounce!) Martini glass, circa 1940. 7-8 ounces of gin and needle-sharp hand-missiles... how could this possibly go wrong?
A souvenir mortar* from a childhood field-trip to Appomattox now sits on a cheap cork coaster as a rest for an active fountain pen.
In my travels, I've found a men's tailoring shop that dispensed brass buttons from a gumball machine, an old tall-standing Jøtul wood stove that now serves as a liquor cabinet, and a delicate paper parasol that softened previously harsh lighting in a converted loft. Simple, cheap, creative, unique, memorable, and thoughtful. While drastic repurposing is often not available for a gent's clothing (one wouldn't swap a waistcoat with a life-vest under a suit), subtlety is explorable, and the mark of good style... with some inevitable and forgivable failures.
