Invite in early spring's warming sunlight by installing drapery hardware that's made to handle the push and pull of daily use: old doorknobs. Scour salvage yards, antiques shops, or flea markets to find the right ones to flank your window. Don't worry if a knob's threaded rod or backplate is damaged or missing; to install, you'll need a dummy spindle (inset, right; under $5 at specialty hardware stores), which anchors to the wall and threads onto the knob. A reproduction rosette like the one shown (inset, left; about $6.49 at houseofantiquehardware.com
) slides over the spindle, covering the hardware.
