Frequent question: What tension should I set my sewing machine?

What is the normal setting for a sewing machine?

Most sewing is done in the 2.0 to 2.5 range. If you are foundation paper piecing, you may want to decrease your stitch length so that the paper tears away easier. Top stitching and quilting are usually done in the 3.0 to 3.5 range. Basting and gathering stitches are the longest, from 4.0 – 5.0.

What should the tension be set at on a Singer sewing machine?

The target figure should be around 30 to 40g. (1-1/4 to 1-1/2 oz) but it does not have to be too precise. However most people don’t have a spring balance handy, so alternatively you can tie a weight of the correct amount onto the thread and then jerk the bobbin gently upwards.

How do I know if my sewing machine tension is too high?

If there are loops on the right side (red thread with black loops), the upper thread tension is too tight. If there are loops on the bottom side (black thread with red loops), the bobbin thread tension is too tight. Most of the time, the upper tension needs to be adjusted.

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.

What tension should I use for stretchy fabric?

Tension: For loftier knits or stable knits, like ponte or scuba knit fabrics, try a lower tension around 2 or 3. Around 4 is usually good for heavyweight knits. The 4-5 Tension range generally yields the best results with light to medium weight knits.

Why is my bottom stitch not straight?

If your thread is pulled tight on the underside and not forming an even stitch then (counter-intuitively) it’s usually the top thread tension that’s wrong. Sometimes very lightweight fabrics such as sheers can get dragged down into the machine so it’s a good idea to use a straight stitch plate.

What tension should I use for thin cotton?

Use size 70/10 for really thin cotton like voile, size 80/12 for light to medium weight cotton, and 90/14 for thick cotton like denim.
