Is your rug tripping you up? Keep cotton flat-weave and other lightweight rugs from slipping around and curling with this tried-and-true trick: Attach a pair of flat, cork-backed rulers along the edges of each corner. Using a large, heavy-duty needle and monofilament, stitch through the rug, and tie it around the ruler in a couple of spots to secure.
