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.
Why are my sewing stitches loose?
The machine is not correctly threaded
If the machine is threaded wrong, not only does it make the thread breaks easier, but is also more likely to create loose stitches. Check the threading to see if the thread has passed through the entire thread guides, the take-up lever and the eye of the needle.
What is staggered stitch?

What is the solution of skipped stitches?
When the stitches randomly start skipping, change your needle. If the stitches return to normal, then the problem was a bent needle.

How do you tell if your bobbin tension is off?
The thread should unwind just slightly and the bobbin case should drop an inch or two. If the thread unwinds without resistance and the case slips to the floor, your bobbin tension is too loose. If the bobbin case doesn’t budge, your bobbin tension is too tight.
What tension should my sewing machine be on?
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 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.
Why does my top stitch look wrong?
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.
What should sewing machine stitches look like?
Machine stitches should look the same on both sides of the seam when you sew patchwork pieces together or when you machine quilt through the quilt’s top, batting, and backing. … The little knot formed between stitches (at each indentation between them) should be invisible, buried in the layers.
What will you do if there is a problem with the stitch tension of the upper thread?
If the tension isn’t perfect, fix it by adjusting the bobbin spring; tighter if the bobbin thread shows on the upper layer, and looser if the needle thread shows on the underlayer. Make another test seam, and examine the stitches, repeating until the stitch is balanced.
What are two consequences that may happen if you cut the fabric improperly?
Problems of stitch formation, giving rise to poor seam appearance and performance; Problems of fabric distortion known as pucker, also giving rise to poor seam appearance; Problems of damage to fabric along the stitch line.
