Sews a 1/4"" seam allowance quickly and accurately. Great for piecing quilts and top stitching for top drop loading bobbin models. The Janome 1/4" seam guide foot is a popular foot with patchworkers for that essential 1/4 inch seam. The guide on the foot enables you to sew a perfect 1/4 inch seam every time. The guide can also be used wherever a 1/4 inch seam is called for but the markings on the needle plate cannot be used, such as when completing a flat-felled seam. Janome Part Number 200318000
