If the upper thread appears as a single line, the lower thread is incorrectly threaded. Instead of the appropriate tension being applied to the lower thread, it is pulled through the fabric when the upper thread is pulled up.
Why is my sewing machine not sewing zig zag stitches?
Try some of the simple things first. Remove the bobbin plate using a screwdriver and then remove the bobbin. Clean out any lint that may be under the bobbin and which may cause your zigzag stitch not to work. Replace the bobbin and the bobbin plate and test your zigzag stitch.
What tension should I use for zig zag stitch?
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 not stitching correctly?
A. Skipped stitches can mean one of two things: needle issues or disrupted timing. First, your needle may be dull or damaged and needs to be replaced. You should also check that you are using the correct needle for the type of fabric you are sewing.
Is a zigzag stitch stronger than a straight stitch?
Though straight stitch is considered as the strongest stitch, zigzag is one of the most durable stitches. There are ways in which you can make the hold stronger. For instance, the triple zigzag is stronger compared to the ordinary zigzag ones.
What makes a sewing machine zig-zag?
When creating a zigzag stitch, the side to side motion of the sewing machine’s needle is controlled by a cam. As the cam rotates, a fingerlike follower, connected to the needle bar, rides along the cam and tracks its indentations. As the follower moves in and out, the needle bar is moved from side to side.
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 should I set my sewing machine to?
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.
Why is my top thread not sewing?
If the top thread is not reaching the bobbin, the threads will not lock properly, resulting in a skipped stitch. Re-thread your machine, both top and bobbin threads, and test. If your machine is still skipping stitches, there may be an issue with the timing, which will require expert repairs.
How do you troubleshoot a sewing machine stitch?

Why won’t my sewing machine needle go up and down?
A disengaged clutch, broken drive belt or internal drive gear failure can prevent the needle from moving. Engage the hand wheel clutch if you have it disengaged for bobbin winding. If the needle won’t move with the clutch engaged, unplug the sewing machine and check the drive belt.
