* Create perfectly spaces pleats & gathers * Easily adjust closeness & depth * Light to medium fabrics Craft & create perfectly spaced pleats & gathers by using the Singer ruffler foot. Easily adjust the closeness & depth using the screw to determine how much fabric is pushed into the attachment each time it tucks. Move the ruffle regulator to determine the frequency of tucks (it can tuck every twelfth stitch, sixth stitch, every stitch or not at all). The foot is recommended to be used with light to medium fabrics.
