Pintucks are little decorative ridges (or tucks), usually sewn in narrow rows. The ridge is created when a narrow piece of cording is placed under your fabric and you stitch on either side of it with a twin needle. To sew them you need a pintucking foot working in conjunction with a pintucking cord guide.
When you want to make pintucks on your Janome sewing machine, the Pintuck Foot And Cord Guide Set is the accessory to use. The set comes with two feet. (The wider one is for heavier cords. The narrower one is for lighter cords.) And two cord guides that correspond to the feet.
Setting up and creating beautiful pintucks is easy with this set.
