Cover up with a breezy beach wrap made from a favorite fabric. To determine how much cloth you'll need, first measure from waist to ankle. Then measure around hips, multiply that number by 2, and add 2 inches. Cut fabric so that one long side falls along the selvage -- we used Indian cotton cut from a 45-inch bolt. With fabric right side down, double-hem each short side 1/2 inch (pressing after each fold). To make the waistband: Double-hem the unfinished, long side of the fabric 1 1/2 inches (pressing after each fold). Leave the selvage edge as is. To add ties: Tuck a 24-inch-long piece of ribbon (ours was 5/8-inch-wide twill) in each end of the waistband, and stitch in place, as pictured.
