For models 1600P and HD9. The ¼” Ruler Foot was specifi cally designed to use for ruler work using Janome quilting rulers. The ¼” cup height moves smoothly alongside the quilting ruler without allowing the ruler to slide over or under. With this foot, the needle drops a ¼ inch away from the ruler to create the quilting line. * This foot cannot be used with sewing machines on which the presser bar automatically moves up and down when free-motion quilting.
