Embroidery Threads

When sewing with metallic
threads, we recommend the use
of the vertical spool pin and the
supplementary thread guide
(optional accessory).

Bobbin Threads

Use white bobbin thread or
match color with fabric.
One of the most important elements in
successful embroidery is the quality of the
thread. We strongly recommend that you
purchase thread from a reputable BERNINA
dealer in order to avoid irregularities, thread
breakage, etc. which so often occur with poor
quality threads.
Embroidery is particularly effective if you use
glossy rayon or polyester embroidery threads
as upper threads. They are available in a wide
range of colors for beautiful embroidery.
