Why is my straight stitch not working?
Change Your Needle Regularly
A blunt or damaged needle is the number one culprit for poor stitch quality and can lead to any number of stitch problems, including skipped and uneven stitches and thread shredding. … A great tip is to place a piece of paper under the foot before loosening the needle clamp screw.
Why does my sewing machine make uneven stitches?
When the bobbin case is threaded wrong, the upper thread and the lower one do not work in sync, forming uneven stitch or uneven feed among layers of fabric. Check the bobbin case and re-thread if needed. The thread should pass through the thread side slot in the case before being brought up to the needle.
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.
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.
How do you put tension on a sewing machine?
Pull some thread off the spool in the machine and cut it close to the spool. Tie two or three overhand knots in the thread, and be sure they are tight. Unthread the needle, and pull the knotted thread through the tension disks down by the needle. The tiny knots often catch bits of lint in the tension discs.
Why are my stitches skipping?
Skipped stitches are usually caused by an old or worn needle. With every stitch, there is friction placed on the point of the needle and with repeated action, the needle experiences abrasion. Over time, the needle becomes dull and doesn’t perform well. This results in skipped stitches.
What is the part of the sewing machine that controls the looseness and tightness of stitches?
Tension controls the looseness and tightness of stitches.
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.
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.
