Janome AcuFeed Zipper Fit (Single) For 9mm #202128007
With many layers of fabric making up those seams, sometimes just pinning in place will cause the zipper and fabric to shift while sewing. Especially when using more difficult fabrics like velvet or satin. By using the AcuFeed Flex Zipper Foot, you'll be able to glide easily over the seam without distorting your zipper.
The Janome AcuFeed Flex Zipper Foot ED (single) for 9mm Machines comes standard with Janome MC15000 and MC14000 machines.
