Thread tension
In order to achieve a perfect seam ap-
pearance and durability make sure the
needle tension is correctly adjusted, so
that the thread interlace is not visible on
both sides of the fabric.
The following is valid for general
sewing work:
Thread interlace is visible on the top side
of the fabric:
• The needle thread tension is too tight .
• The thread tension must be lowered.
Thread interlace is visible on the under-
side of the fabric:
• The needle thread tension is too loose.
• The thread tension must be raised.
• For fancy stitches, buttonholes and
darning the thread interlace should be
visible on the underside of the fabric.
