You asked: How do you adjust the tension on an old sewing machine?

Why is my thread bunching underneath?

A: Looping on the underside, or back of the fabric, means the top tension is too loose compared to the bobbin tension, so the bobbin thread is pulling too much top thread underneath. By tightening the top tension, the loops will stop, but the added tension may cause breakage, especially with sensitive threads.

Why is the tension wrong on my sewing machine?

Needles, threads, and fabrics: Different thread sizes and types on top and in the bobbin can throw off basic tension settings. A needle that’s too large or small for the thread can also unbalance your stitches, because the size of the hole adds to or reduces the total top tension.

Why is my sewing machine not picking up stitches?

Skipped stitches can mean one of two things: needle issues or disrupted timing. First, your needle may be dull or damaged and needs to be replaced. You should also check that you are using the correct needle for the type of fabric you are sewing.

What tension should I use for cotton?

Cotton requires a moderate tension setting, usually between three and four. Always start adjusting your tension settings with your upper tension.

Why is there a need to put oil on slots after dusting the sewing machine?

In time, lint and dust that are allowed to accumulate in a sewing machine can become soaked with oil and/or lubricant and interfere with the operation of the machine. When this gummy grime is removed, the machine will work more freely, and adjustment may not be necessary.
