Sewing preparation
Important facts about thread and needle
The thread is chosen accordingly to the purpose. For a perfect sewing result,
thread and fabric quality play an important role. It is recommended to use
quality brands.
Cotton threads
̶ cotton threads have the advantage of being a natural fiber and therefore
are especially suitable for sewing cotton fabrics
̶ if cotton thread is mercerized, it has a slight sheen that is not lost with
washing
Polyester threads
̶ polyester thread has 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
̶ 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
Thread
Needle, thread and material
Care must be taken when choosing needle and thread.
The correct needle size depends on the selected thread and fabric. The fabric
weight and type determine the thread weight, needle size and point form.
ATTENTION!
Check the needle condition.
As a guide: Replace the needle before starting a new sewing
project. A defective needle does not only damage the sewing
project but also the sewing computer.
