The Janome Convertible Free Motion Quilt Foot Set For MC9900 is for 9mm high shank machines without presser foot height adjustment. This foot is not suitable for models MC 12,000 & MC 15,000. This clever set is an update on the standard free motion foot. It consists of the foot holder and three interchangeable feet offering more convenience, improved operation and added value. The design of the foot holder offers a quieter more stable movement and means that no lever is placed over the needle clamp screw as with the standard free motion foot. Movement is linked solely with the presser foot bar rather than the needle bar resulting in a quieter operation at higher speeds. In addition, the fabric layers can be moved more easily as there is no delay between ascent of the needle and that of the foot after each stitch. The clearance between the foot and the fabric can now be adjusted with the top screw so that the foot simply skims the surface without impairment. The interchangeable feet attach to the holder with a screw for maximum sturdiness and safety. They consist of a closed-toe foot, an open-toe foot and a clear view foot which is ideal for uneven surfaces and evenly spaced quilting. The clear view foot is also designed with 1/8" markings for even spacing when "Echo Quilting" eliminating the need to mark out your fabric beforehand. The Janome Convertible Free Motion Quilt Foot Set For MC9900 includes: * Closed Toe Foot for general use with lace and catchable fabrics. * Open Toe Foot for general use and extra visibility * Clear View Foot for uneven surfaces and evenly spaced quilting.
