The standard position is between “4” and “6”. However, a
sewing test should always be done to check for the proper
thread tension.
Thread tension may need to be adjusted with the use of
different thread, fabric or stabilizer fabric.

Correct thread tension
Adjust so that the lower thread stitch width on the reverse
surface of the fabric is about one-third of the total width.
Correct tension is important because too much or too little tension
will cause poor quality embroidery or your fabric to pucker.
