Often two-ply core threads are offered by the thread manufacturers with
the same designation as three-ply polyester fibre threads (3cyl.-spun).
This causes uncertainty with regard to twisting and thread thickness.
When in doubt, unravel the thread and check whether it is twisted 2- or
3-ply. The label no. 120 on the thread reel of a core thread corresponds
e.g. to the thread size Nm 80/2 (see table values in brackets).
In case of monofilament threads you can use needle threads and hook
threads of the same thickness. The best results are achieved with soft and
elastic threads (software) of the thread thickness 130 Denier.
