The BERNINA ‘needle-punch’ tool is a cluster of three needles that are used to punch fibers through fabric. This process is normally performed as free motion sewing but can also be done in the embroidery hoop.
The tool most suitable for hoop work is the Rotary Hook Punch tool, since the presser foot also allows yarn, ribbon and so on to be fed through the foot under the needles, and includes a guide as part of the accessories.
