Medion LIFE SM60 Manual De Instrucciones página 229

Raise the needle to its highest position and select the program for the
top bar again.
Then sew a few stitches for the top bar as you did for the bottom bar.
Finally, we recommend setting the stitch length to "" and sewing a few
more stitches so that the threads are better linked and the buttonhole
does not fray so quickly.
Finally, separate the fabric between the seams with the enclosed cutter.
Do this carefully to ensure you do not damage any of the bars.
TIP
We recommend putting a pin in front of the top bar to stop you cutting
through it.
10.12.2. Reinforced butt onholes
We recommend reinforcing heavy-duty buttonholes with thread (crochet
thread, reinforcement yarn or buttonhole yarn).
Cut a piece of reinforcement yarn to fit the size of the buttonhole and
place it around the buttonhole foot.
Feed the yarn into the hook at the rear end of the presser foot and then
bring the yarn forwards and fasten it on the front hook with a knot.
Sew the buttonhole as usual. Ensure that the stitches catch the rein-
forcement yarn completely.
When the buttonhole program is finished, take the fabric out of the
sewing machine and cut off the ends of the reinforcement yarn.
TIP
You should practise a few buttonholes on a piece of cloth first in order to
learn how to use reinforcement yarn.
