Keep track of beach essentials -- sunscreen, novels, flip-flops -- by sinking them in a corner pocket. To make four pockets, take a sheet or a lightweight blanket and two 14-inch squares of linen or cotton. Cut each square into two triangles. Fold all edges over 1/2 inch, and press. Fold long edge of each triangle over another 1/2 inch, and sew across to hem. Pin the triangles to the corners of the blanket. Sew the short sides of the triangles to the blanket's corners, and start packing.
