What should tension be set on sewing machine?
The dial settings run from 0 to 9, so 4.5 is generally the ‘default’ position for normal straight-stitch sewing. This should be suitable for most fabrics. If you are doing a zig-zag stitch, or another stitch that has width, then you may find that the bobbin thread is pulled through to the top.
Why is my sewing machine looping 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’s wrong with my sewing machine tension?
When sewing fabrics together problems can occur when the thread tension is not correct, the needle or bobbin is not inserted properly, or the machine is not threaded correctly. … Always place two layers of fabric together when producing a sewing sample to check thread tension, needle type and stitch length.
What tension should I use for stretchy fabric?

Why can’t I sew a straight line?
Since the needle is constantly moving, you will not sew straight if you watch it as you stitch. The seam guide does not move so it’s much better to focus there as your fabric moves along, resulting in much straighter seams.
