Use this adjustable foot to sew along a ¼-inch-thick plexiglass ruler and create decorative quilt designs such as lines, feathers and circles. The markings on the inside and outside allow for precise sewing, and the dial lets you adjust the height of the foot individually to the fabric thickness. The presser foot #72S can be replaced without cutting the thread. This makes it easy to switch from Rulerwork to other applications. Both presser feet are compatible with the couching inserts and the echo quilting clips.
