Bernina Foot No 31
For sewing pintucks, you’ll need a double needle with a width between the two needles corresponding to the width of the grooves on the foot (up to 3mm).
This way the finished tucks will be the matched in size to the grooves in the pintuck foot. When sewing several parallel pintucks, these grooves ensure an even distance between rows. The generous cutout in the center of 5-Groove pintuck foot # 31 ensures a good view of the area to be sewn.
The pintuck foot is also ideal for sewing braids, trim, and mini-piping, as well as for elastic gathering.
