I would like to replace the knobs on my cabinets, as they're dull and plastic-y and quite a few have permanently come loose from the bolts that hold them on the cabinet doors. But each knob also has a dull and plastic-y escutcheon. And the wood under the escutcheon has an imprinted outline of the escutcheon pattern, and has weathered differently. Which means I would either need to re-finish the cabinet doors, or replace the escutcheons with even larger ones to hide the variations.
Today's word is brought to you by autocorrect: I was trying to text my friend about taking my spare Costata romanesca squash seedlings, and it kept changing to "Costa Roman escutcheon". I thought it an odd word for autocorrect to know - and odd to go there when it's such a short trip to Romanesque. But that's autocorrect for you.
