Thread Tension
When buying sewing threads, you should bear in mind that your creative 4874 uses
considerably more than a conventional sewing machine, so you will need to buy
correspondingly larger units of thread.
Overlock thread is available in cones (2,000-5,000 m) or mini-kingspools (1,000 m) in a
wide range of colors. Of course you can also use standard all-purpose threads.
To prevent overlock seams from expanding excessively, we recommend an overlock thread
made from 100% polyester, gauge No. 120.
Textured thread can be used as a looper thread and results in soft and non-bulky seams.
Textured threads are particularly suitable for use in sewing rolled hems.

Thread table for 2-, 3-, and 4-thread overlock seams
For the top and deco cover stitches many decorative threads can be used. Try heavier and/
or textured threads especially for the deco stitches in the decorative loopers.
Test sew with the thread and fabric you will be using. Adjust tensions as necessary (see
pages 7-16 - 7-21). Remember some threads will work better than others.
