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 zigzag puckering?
The stitches in your fabric will pucker if there is too much tension in the seam thread. It is a dead give-away that the crafter did not sew the seams properly. A zig-zag stitch is a side to side stitch used for decorative sewing, stretch fabrics, and seam finishing.
What is tunneling in sewing?
Tunneling is what happens when there is a large bump in between your two rows of stitching. To avoid this, I’ve found it helps to increase your top thread tension. Your machine may vary, but I usually set my tension to 3. If possible, you should also decrease your bobbin tension as well.
How do you fix the zigzag stitch?
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.
Why does my sewing machine keep bunching the thread?
What should I do if I experience thread bunching? As “thread bunching” occurs on the underside of the fabric, some people think it is due to the lower thread. They check whether the bobbin is sitting correctly in the bobbin case or even replace the bobbin. … On many models, the upper thread tension is set automatically.
Why is my thread bunching 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 is the tension wrong on my sewing machine?
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.
