Checking
the
thread quality
Does your thread fluff up or break very quickly? This indicates poor
quality thread or that the thread is old (overlaid.
Low-quality threads
may cause damage to
the thread tensioning system of your overlocker
machine in the long term.
Check the quality of the thread by pulling strongly on the thread with the
thumb nail and index finger nail.
Fabric puckers
Reduce the thread tension. See
