To keep your kitchen sink uncluttered, shop flea markets or housewares stores for pretty little trays to hold sponges, brushes, and dish and hand soap; the trays minimize spillover to the countertop and enable you to remove multiple small items quickly when you need to clear the sink. Find a glass bottle with a spout in which to decant your dishwashing liquid; the main supply can hide under the sink. A tenet of space saving: Let items serve double duty. When you have only a few things to wash, use a wire rack atop a sheet pan to drain dishes. They vanish into the cupboard after dishes dry, leaving valuable open workspace near the sink.
