Sometimes your clutter threatens to take over your life — or at least your countertops, cabinets, coffee tables, drawers, and dressers. You’ve tried organizing it in Tupperware and plastic cups, but that strategy gives your home a perpetual morning-after-a-kegger look. Soho Spice Racks ($50 to $80) are a little sleeker and lots more sensible. The jars, which seal up airtight, have magnets on the bottom and stick to the line’s freestanding or mountable stainlesssteel boards of various sizes — or to any metal surface, for that matter. Kristen Gaughan, owner of Urban Living Studio (58 Clarendon Street, Boston, 617.247.8150), says they’re highly customizable: fill them with office supplies and stick them on the metal edges of your cubicle; mount a board inside your bathroom cabinet and load the jars with cotton balls, Q-tips, and other toiletries; give your hardware kit a sleek makeover; or fill them with sweets for guests. After all, now that your living room is tidy, isn’t it time for a house party?
