The Ruffler Foot is a real time saver when making anything with ruffles or pleats. Gather or pleat one fabric layer and attach it to one or more flat layers in one operation. It can also be adjusted to make repeating tucks and narrow pleats. Includes instructions. The I Adore My Ruffler Bookis "the must have book" to learn to use this foot to it's fullest. It's a "video book" that contains private links online that show you how to do the techniques in motion! The Ruffler Attachment is Made in Japan and superior quality. This is the one recommended by Debra Justice in her book.
