Approximately 3 to 4 yards of 45-inch-wide fabric is needed to make a crib bumper, depending on the pattern used. If the bumper is to have piping, add another 1 to 1 1/2 yards of fabric, and if the pattern calls for ruffles, add another 2 yards.
If cotton cording is also used for decorating the bumper pads, 6 yards of cording is needed. Other materials needed for crib bumper pads include foam pads and thread. Bumpers for a bassinet typically take about 2 1/4 yards of fabric. Padded bumper pads inside a crib or bassinet keep babies from bumping their heads against the sides or slats.
