Green Screw Bobbin Case

Adjusting The Tension
If you are using a heavier thread, you would need to loosen your tension. If you are using a thinner thread, you would need to tighten your thread.
Thread Weight
If you are unfamiliar with thread weights, the lower the number, the heavier the thread. For example, a 30 wt thread is heavier than your 60 wt thread. A 90 wt thread is thinner than the 60 wt.
