An accordion pleat is a drapery header type in which the fabric is formed into the shape of a sharp ‘Z’. The shape can be made by sewing the top of the fabric together and pressing, or it can be done with the use of hardware and pressing. An accordion pleat is similar to a knife pleat in that it has sharp creases that add volume, but it is on a smaller scale. The sharp crease that is formed at the header then flows to the bottom of the drapery, creating a uniform look from top to bottom. Most commonly, an accordion header is mounted with hardware just below an exposed track, to give the drapery an airy, floating feel. It can also be on a hidden track or a curved track and the drapery can be hand drawn, cord drawn, or motor drawn..
