Pintuck Foot with 5 Grooves #31 is specifically designed for sewing even pintucks on medium-weight fabrics. To achieve perfect pintucks, you’ll need to use a double needle with a width that matches the grooves on the foot, allowing for sizes up to 3mm. This design ensures that the finished tucks align precisely with the grooves, creating uniformity in size. When sewing multiple parallel pintucks, the grooves maintain consistent spacing between rows for a polished look. The generous cutout in the center of the foot provides excellent visibility of the stitching area, making it easier to sew accurately. Additionally, this versatile foot is ideal for sewing braids, trim, mini-piping, and elastic gathering, enhancing your creative possibilities.
