#12 Foot New Bulky Overlock
The hero of custom piping to accent seams, couching bulky yarns or cording, is a dual duty foot! It was originally designed to sew together heavy sweater knits, which it is still great at.
The #12 works with all New Style BERNINA sewing machines with a max stitch width of 5.5 mm. Check out the #12C for machines that does a 9 mm max stitch width.
