Why is my stitch length uneven?
The Problem: Stitches are coming out uneven or skipping entirely. THE SOLUTION: Odds are, the secret culprit here is a needle that is broken, bent, or otherwise damaged. Experts recommend that you replace your needles for every 16 hours of stitching time.
Why does my straight stitch look like a zig zag?
The stitch on the left had too much tension, so it pulled the fibers of the fabric together and caused a small lump between zigzag points. … The stitch on the far right has loops where there should be points, which is what happens when the upper threads are too loose.
What should my sewing machine tension be set to?
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.
How do I know if my bobbin tension is correct?
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.

Why is my sewing machine not doing zig zag?

How do you adjust tension on a sewing machine?
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.
Why is my sewing machine skipping zig zag stitches?
Make sure that the thread is in the tension disk and the spool is placed correctly on the machine. Also, double-check to see if the bobbin is in the correct way and threaded tightly. Sometimes, a poorly wound bobbin is the culprit for skipped stitches. Good quality thread also plays a part in nice and even stitching.
How do you know thread tension is correct?
A correct thread tension looks smooth and flat on both sides of the seam. The needle and bobbin threads interlock midway between the surfaces of the material.
What tension should I use for cotton?

Why does the thread bunch up underneath?
Your Thread Tails Are Too Short
If the thread tails that come out of your bobbin are shorter than two inches, they may get sucked into your sewing machine when you begin to sew. This can cause thread bunching underneath your fabric.
