Bulky Overlock / Braiding Foot #12
The product is Generic

This foot is especially well suited for sewing seams in thicker jerseys and sweater knits using an overlock stitch. Couching thicker yarns and cords, and piping
One side of the foot is higher than the other to accommodate the uneven layers encountered when seaming sweater knits or covering and inserting piping (especially corded piping)
The extra space under the foot helps prevent knit fabrics from stretching as they are stitched
The same groove under the foot makes it well suited for making corded piping. In many applications, corded piping can be made and applied in one operation with the help of Foot #12C (and #12C will accommodate thicker cording such as for luggage and upholstery applications)
