SINGER 9910-WORKBOOK Quantum - Manual (Page 14)

♦Lower the presser foot to hold the button in place.
♦Turn the hand wheel forward; adjust so that the needle goes into either
the right or left hole.
♦Adjust the stitch width dial to fine tune the swing of the needle into the
other hole.
♦ Recheck the swing of the needle into the other hole and then use the
foot control to stitch 5-6 stitches.
♦ Before removing the button and fabric from the machine, change to
straight stitch. Leave width at current setting and stitch in place for
three stitches. This forms a tie-off on the back side to secure the
button.
♦Apply a liquid fray-preventer on the backside of fabric on the knots.
Trim threads after they dry, being careful not to cut thread knots.
Note: Remember to raise the feed dogs when finished.
