You must remember to lengthen the stitch for heavier fabrics, multiple layers of fabric and thicker seams. Some of these seams are:
Common two layer seams
Curved two layer seams
Top stitched three, layer seams
Top stitched four layer seams
When you have two seams crossing each other with considerable thickness, sew slowly and carefully so the seam will be as strong as possible in this area.
FASTENING A SEAM (Backtacking)
Be sure both threads are drawn back under the presser foot. Lower needle into fabric about ½ inch from beginning
of seam. Raise the Stitch Length Control to R and stitch in reverse until
needle reaches beginning of seam. Lower the control to again stitch forwards and complete seam. When you reach the end, raise the control and sew back over ½ inch of completed seam.
