Whenever my friend Robin visits (use to be from Key West, now from Wisconsin), one of our rituals (we have several) is to go to Cape May Point, where the ocean and bay meet, and sift through the millions of pebbles on the beach there. We're not looking for Cape May Diamonds (quartz) like everyone else, but we discovered onetime that our pebble selection was not without design. It seemed to us that the pebble you have in your hand determines which one you'll pick up next; that you unwittingly make sets.
Maybe because there are so many you need some framework to make your choices or, as I prefer to think, perhaps you just can't help it.
(Wish you were here, Robin, for beachcombing and philosophizing, and, while we're at it, quaffing.)
Last year I bought the adorable bijou box at right for something like eighty bucks; it came with 8 pans of color, and I added 4 more.
Yesterday I got the empty box at left from Wet Paint--it has 12 small wells, not pans--for fourteen dollars!
Both boxes are metal and have a thumb ring underneath.
