Hinged Slant-shank Zipper Foot 161166 - Singer" /> This is the best sewing foot for inserting zippers, snap tape, and more. The toe of the foot is narrow for more visibility and precision. Adjust the needle to either the right or left to sew both sides of your zipper easily. You can also use it to attach piping or decorative cording. These zipper feet can also be used to apply piping or welting that is too large to fit in the groove on the pearl and piping foot.
