The Brother SA226CV Top Stitching Foot Set is designed for the 2340CV Coverstitch Machine and allows you to create perfectly spaced topstitching for a professional finish. This set includes a presser foot that works with 3mm or 6mm (approximately 1/8 or 1/4 inch) wide cover stitches. To use, set the T1/T2 presser foot, set up your machine for a cover stitch with the desired width, open the seams, align the fabric joint with the groove of the presser foot, and sew. This foot set ensures clean, precise topstitching on a variety of projects.
