BERNINA #07 Tailor Tack Foot
This foot can be used for marking seam lines, sewing elegant embellishments, imitation hemstitch (fagotting), fringe, and 3D effects.
When sewing together two pieces of fabric, the thread tension is loosened slightly, so that the thread can pass easily over the ridge in the center of the foot. The zigzag stitch used forms loose loops which then slide off to the back thanks to the special V-shaped opening on the foot.
For marking seam lines or darts, the fabric is carefully pulled apart after sewing.
