Decrease tension Increase tension
CHECKING FOR CORRECT TENSION OF THREAD
The good looking appearance of your straight stitching is mainly determined by the balanced tension of the top thread and bobbin thread. The tension is well balanced when the two threads lock m the middfe of the layers of fabric when straight stitching.
You can achieve balanced tension by regulating the Top Thread Tension Control (17). if the upper thread appears to be too tight, dial left (lower numbers) to decrease tension. If the upper thread is too loose, dial right (higher numbers} to increase tension.
