Pleated drapes are conventionally made with one panel
or by sewing together two or three panels of drapery
fabric each of which may have an initial width in the
order of 44 to 50 inches and each of which may have an
average of ?ve sewn pleats to produce a ?nished pleated
drapery width in the order of 2,1 inches per panel. It
is desirable that the pleats be uniform in depth and uni
formly spaced from each other and that a uniform margin
