Jaguar Stitch Guide Foot.
The scale in the presser foot can be used for perfect topstitching on both straight and curved lines. Each divisional mark equals 2 mm.
1. Select straight, zigzag, or decorative stitches.
2. Sew the stitches keeping a certain seam allowance.
To sew a curve, sew so that the fabric edge becomes a right angle against the presser foot.
