In the 15th section of the BERNINA presser-feet online tutorials we'll present you the Bulky overlock foot no. 12/12C. Due to its especially wide groove on the sole the bulky overlock foot is suitable for sewing bulky knits and other thick fabrics. However, it is especially ideal for making and attaching piping and couching strings of beads on garments and home decor projects. One side of the sole is deeper than the other, allowing for smooth feeding of uneven fabric layers, e.g. when hemming knits. Presser foot no. 12 is suitable for BERNINA machines with 5.5mm stitch width, foot no. 12C for BERNINA machines with 9mm stitch width.
