Adjust the Stitch Length
To make longer stitches, set the stitch length to a higher number. On many sewing machines, four is the longest possible stitch length and two is average.
To make shorter stitches, set the stitch length to a lower number. At a zero, the sewing machine may not actually make stitches, since the needle will go up and down in one place.
Cut a small scrap of fabric, preferably the same type you want to sew with.
Sew a few test stitches on the scrap. Examine the stitches to make sure they’re the length you want.
Adjust the stitch length again as needed.
Adjust the Stitch Style
Set the sewing machine to a zigzag or decorative stitch by turning the dial or setting the electronic control.
Cut a small scrap of fabric, preferably the same type you want to sew with.
Sew a few test stitches on the scrap.
Examine the stitches to make sure they’re the type and size you want. Zigzag and decorative stitches can look very different depending on the stitch length. For example, a scalloped decorative stitch may only look right with the stitch length set at one.
Adjust the stitch length as needed and repeat Step 3 and Step 4.
Adjust the Tension
Set the upper tension tighter by turning the dial slightly to the right, or looser by turning the dial slightly to the left. (Or by using the electronic control if the sewing machine has one.) This adjusts the tightness of the main thread.
Set the lower tension slightly tighter or looser using the dial or electronic control. This adjusts the tightness of the bobbin thread.
Cut a small scrap of fabric, preferably the same type you want to sew with.
Sew a few test stitches on the scrap. Examine the stitches to see if they’re too tight or too loose. The stitches should lie flat against the fabric, without pulling the fabric or making loops that stick out.
Repeat Step 1 to Step 4 again as needed.
