Husqvarna Viking Overcast Foot (J)
The J Foot is used for overcast stitches that stitch to the side and can pucker or curl the fabric to stop it from curling under. The tiny wire on the edge of the foot also stops the curling of the fabric edge. Consult the Husqvarna Viking Infodisplay which recommends the J Foot for many overedge stitches.
