Embroidery Needles
• use correct needle size for each thread
• exchange needle regularly
Needle, Thread and Fabric
Care has to be taken when combining needle and thread.
The correct needle size does not only depend on the chosen thread,
but also has to be well-suited to the fabric used. The fabric weight
determines the thread weight and needle size.
Needle/Thread Combination
In order to check the needle/thread compatibility, the correct size
thread must correspond with the correct size needle.
Correct Needle/Thread Combination
When sewing, the thread should travel smoothly down the long
groove on the back of the needle. The thread can be secured
optimally.
Too Thin Thread or Too Thick Needle
The thread does not travel smoothly in the groove. Faulty stitches
and damage of the thread can occur.
Too Thick Thread or Too Fine Needle
The thread rubs on the edges of the groove and can get jammed.
This can break the thread.
