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.
What should my stitch 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.
How do you adjust the tension on a zig zag stitch?
Zig zag stitch can be adjusted by changing the settings on the machine. A higher number on your stitch length makes the zig-zag longer and the width dial will indicate the width of the stitch and change it to wider or narrower.
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.
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.
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.
What width should my sewing machine be on?
A straight stitch has no width so it makes sense to set the dial at “0”. However, each machine varies so you will want to set the Stitch Width dial at the position where the needle is centered over the stitch plate. This will give you the most accurate seam allowance.
What thread tension should I use for denim?
Tension is ideal up to 6, but is too high after that and pulls the top stitch into a flat line. Regular thread, bobbin thread view. The bobbin stitches clear up around 6 but don’t improve much after that.
Does a zig-zag stitch stretch?
A zigzag stitch is a great way to seam knit fabrics. Its inherent stretch allows for the fabric to stretch and move without fear of popping a seam. On light to medium weight knits, try using a stitch length of 1.5 and a width of 5.
When would you use a zig-zag stitch?
The Zig-Zag Stitch is a very versatile stitch. Use it for seam finishing, applique, bartacks, satin stitching and more. For some sewing techniques with this stitch, it can be helpful to use a Satin Stitch Foot to help prevent the fabric from puckering.
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.
