How do you adjust tension on a sewing machine?

Adjusting the tension on a sewing machine is best achieved by turning the tension dial or knob while testing on scrap fabric. This process allows the user to see how the adjustments impact the sewing outcome in real-time. Proper tension is crucial for achieving even and balanced stitches; if the tension is too tight, the fabric can be pulled and puckered, while if it's too loose, the stitches may become skipped or looped.

Using scrap fabric during this adjustment is important as it simulates the conditions of the actual sewing project, enabling a more accurate fine-tuning of the tension settings. The sample fabric should ideally be the same type and weight as the fabric intended for the final project, ensuring that the adjustments made will work effectively when applied.

While changing the needle type, replacing the thread spool, or adjusting the length of the stitch are important aspects of sewing that can affect overall results, they do not directly impact the tension setting as effectively as adjusting the tension dial or knob does. Tension specifically relates to how tightly the threads are pulled together when sewing, which is solely controlled by the tension settings.
