All machines sew straight stitch, both forwards and in reverse. It is used for seams and hems on all types of non- stretch fabrics. Length can be adjusted to suit the thickness of the fabric. It is used in many crafts like quilting and patchwork.
Zig-zag stitch
A zig-zag stitch can be used on most types of fabric, and is especially useful for fine and stretchy materials, e.g. lace and for sewing on elastic. It is used for finishing seams and for appliqué.
Buttonhole stitch
Most modern machines have a buttonhole function; it can be done in four stages or automatically. It is useful for making garments and upcycling items.
Blind stitch The blind stitch can be used on most types of fabric, for blind hemming, shell edging or decoration.

How a sewing machine stitches • There are two threads involved – the thread from the spool and the thread from the bobbin.
• The stitch is made when these two threads twist around each other.
• The interlocking takes place between the two layers of fabric.
• If the tension on the thread is too loose or too tight the stitches won’t form properly.
