BERNINA Adjustable Ruler Foot with Slit #72S allows you to sew along a 1/4-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. Thanks to the slit in the Adjustable Ruler Foot with Slit #72S, you can change a sewing foot without having to cut the thread. This allows an easy transition from Rulerwork to other applications. For free-motion quilting; the foot is compatible with Echo-quilting Clips or Combine with Couching Inserts for couching. For 5.5 mm and 9 mm machines.
