This foot is used for attaching piping cord. It's it the exact same foot the professionals use when adding any piping. This foot is for Janome sewing machines that have a 9 mm zig-zag stitch width. The left or right cut-out under the foot helps keeps the fabric wrapped around the cord in place, while the machine sews it firmly in position. Maximum cord size is 5 mm.
* This foot will work on all 9 mm Horizon machines, such as the 7700, 8200, 8900, 9900, 12000, 14000 and 15000.
