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 cause skipped stitches if there is too much play in the long
groove or eye of the needle.
The thread can break and become jammed if it frays on the edges of the long groove and
is not guided optimally through the eye of the needle.
