What settings should I use when sewing with the Non-Stick Foot on specialty fabrics like leather or vinyl?

Snap on the Non-Stick Foot, select the desired stitch, and adjust the stitch length — the stitch length should frequently be increased to avoid perforations in the seamline. If fabrics need to be pinned together, pin only in the seam allowance or use paper clips to avoid unwanted pinholes. After stitching, use a cool iron and pressing cloth to press seams. (Page 16)
