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 stitch loose?
The middle row of stitches on the swatch is very loose in addition to not looking right. Solution: Rethread the machine. If that doesn’t work, adjust the tension. Explanation: When the thread loops on the backside of the fabric, that’s an indication the upper thread is not threaded correctly.
What should my thread tension be?
Remember, most tension discs close when the presser foot is down, so be sure to thread the machine with a raised foot. A good habit is to put the spool on the machine, and pull out 18 inches of thread.
Why is my bottom stitch looping?
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.
How do you fix thread tension?
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 is a 3 step zigzag stitch?
Three-step zigzag: When used on the widest width, the ordinary zigzag stitch pulls the fabric into a tunnel and the fabric rolls under the stitch — not very desirable. … The needle takes three stitches to one side and then three stitches to the other side, keeping the fabric flat and tunnel-free.
Why are my stitches 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.
