Thread Selection
For a perfect sewing result, thread and fabric quality play an important role.
We recommend purchasing quality threads to achieve good sewing results.
• Cotton threads have the advantage of being a natural fiber and therefore are especially suitable for
sewing cotton fabrics.
• Mercerized cotton threads have a slight sheen that is not lost with washing.
• Polyester threads have a high tensile strength and is particularly colorfast.
• Polyester threads are more flexible and are recommended where a strong and elastic seam is required.
• Rayon threads are made of natural fibers and have a brilliant sheen.
• Rayon threads are suitable for decorative stitches and achieve a more beautiful effect.
Needle/Thread Combination
The needle/thread combination is correct, when the thread fits perfectly into the long
groove and goes easily through the needle eye. The thread can be optimally sewn.
The thread can break and skipped stitches can occur when there is too much clearance in
the long groove and the needle eye.
The thread can break and get stuck when the thread scrapes against the edge of the long
groove not fit well into the needle eye optimally.
