Janome Center Guide Foot (3 - Needle Type CoverPro Machines).
The Janome Center Guide foot can be used on all the CoverPro Machines with 3 Needles.
It is used for lining up the center of a two or three needle stitch with a previously sewn seam. This attachment is especially useful on sportswear and allows you to tack down already sewn seams, give extra strength to seams that come under strain, or simply give a finished decorative effect.
