A fabric-covered button includes a button body with a domed head to be wrapped by a piece of fabric, a retainer washer of synthetic resin adapted to fit forcibly over a boss projecting rearwardly from the domed head and to press an edge portion of the fabric piece against a peripheral flange of the domed head, and a fastener having a shank adapted to fit forcibly into an axial hole in the boss. Either the boss or the shank has at least one axial slot which allows air to escape from the hole in the boss when the shank is forced into the hole. |
