The Brother 5mm Picot Foot is a genuine Brother accessory designed to roll fabric edges and hem stitch simultaneously. Similar to a narrow hemmer foot, the Picot Foot creates a beautiful shell-like edge on lightweight fabrics. The groove on the sole of the foot is specifically designed to match the width of the picot stitches, ensuring perfect stitch formation. This groove helps the fabric feed evenly while the stitches are being created, making it easier to achieve neat, consistent picot edges for your sewing projects.
