A short dictionary entry defining 'plait' as a braid, a flat fold in a garment, and a straw braid used for hats. It describes how straw plait is named by place (Leghorn, Tuscan, Dunstable), strand count, or character, and outlines preparing the straw by cutting, bleaching with sulphur, splitting and plaiting. It explains the over-and-under movement of the 13-strand Leghorn plait and the flattening of finished plait between rollers.
