Buttonholes - Important Information
Thread Tension
• thread the bobbin thread through the finger of the bobbin case = the bobbin
tension is a little tighter
• this gives the beads on the right side of the fabric a slightly rounded
appearance
• the buttonhole looks more attractive
• cord reinforces buttonholes and enhances their appearance
• sew both beads at the same speed
Marking Buttonholes
Manual Buttonholes
• mark the buttonhole length in the desired
position
• use Buttonhole foot No. 3
Automatic Buttonholes
• mark the length of just one buttonhole
• after sewing the first buttonhole, the
length for all subsequent buttonholes is
automatically programmed
• mark only the beginning of all subsequent
buttonholes
• use Automatic buttonhole foot No. 3A
Keyhole Buttonholes
• mark the bead length only
• the correct length eye will be added when
the buttonhole is sewn
Test Sewing
• always sew a test sample on the fabric
with stabilizer you intend to use
• select the buttonhole type you intend to
use
• sew the buttonhole in the same direction
on the fabric (with or against the grain)
• cut the buttonhole open
• push the button through
• adjust the buttonhole length if necessary
Corrections
To Adjust the Bead Width:
• alter the stitch width
Altering the Stitch Length:
• any alterations to the stitch length affect
both beads (more dense or less dense)
• always reprogram the buttonhole after
any changes to the stitch length
If a buttonhole is to be sewn at right angles
to a seam, we recommend the use of the
height compensating plates for buttonholes
(available as optional accessory). Place the
plates from the back between fabric and
bottom of slide foot up to the thick part of
the fabric and push to front.
Using the compensation plate (in some
countries only available as optional
accessory) is recommended when sewing
buttonholes in difficult fabrics. It can only
be used with the Automatic buttonhole foot
No. 3A.
