Why is my zigzag stitch sewing straight?
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.
Check the Needle: Ensure that the needle is inserted correctly and securely. A bent or dull needle can cause irregular stitches. Replace it if necessary. Thread Tension: Incorrect thread tension can affect the quality of the zig-zag stitch.
Set the machine for zigzag stitch. For machines with adjustable stitch length and stitch width, use with a width setting of at least 5.0mm and a length setting of approximately 2.0mm. Use an Open Toe Foot (additional accessory for some machine models) so that the area in front of the needle is unobstructed.
What tension should I use for the zigzag stitch? The thread tension plays a significant role in stitching properly. Normally a sewing machine has a setting options dial from 0 to 9. The default 4.5 is considered as an ideal setting for zigzag stitch on almost all types of fabrics.
Loosen the Needle Tension
The first thing that can cause seam puckering is tension. ZJ recommends loosening the needle tension on your machine and trying the line of stitching on your test sample again. It is always a good idea to retest the stitching after every adjustment made, that way you know what fixed the issue.
The zig zag stitch is a strong stitch, but if the tension is too tight the stitch will pucker and snap. Always check your sewing machine tension before trying the stitch on new fabrics.
This is actually not an uncommon issue with machines and zig zag stitches and it doesn't always have to do with thread tension. I usually see this issue myself when sewing with lightweight knit. It usually means the fabric doesn't have enough stability so the stitches start to pull the fabric towards itself.
The nylon thread proved stronger. Similarly, straight seams held up better than zigzagged ones. A zigzag seam concentrates force at the points of the zigs and zags, while a straight seam spreads force across a long line, Holly says. It turned out that a strong seam can be very tough to tear.
One of the most common uses for the zigzag stitch is to sew stretchy materials. When sewing a material that stretches, such as knitted fabrics and neoprene, it's essential to use a stitch that can stretch with the fabric.
Sew a line of straight stitches and a line of zig-zag stitches to determine if your sewing machine tension is correct. The straight stitches should be even, and in alignment on both sides of the fabric. The zig-zag stitches should be perfect zig-zags and not look like Ys on either side.
How do I know if my bobbin tension is correct?
To test if the tension is correct, insert a bobbin in the bobbin case. Then hold it up by just the thread, the bobbin case shouldn't move. Give a little jerk on the thread and if the bobbin case slides down slightly, then the tension if perfect. If it drops freely, then it's too loose.
Disadvantages: Sometimes difficult to avoid puckering the seam allowance. If not pressed properly, zigzag stitches may leave an impression on outer side of lightweight fabric. Yarns not secured by stitching may still ravel if garment is washed frequently.
Do you have to backstitch a zigzag stitch? You should backstitch zigzag stitches to prevent the stitches from unravelling. To do this, simply use the reverse function on your sewing machine to stitch a few stitches backwards, then continue sewing forwards again.
Cause. Tension pucker is caused while sewing with too much tension, thereby causing a stretch in the thread. After sewing, the thread relaxes. As it attempts to recover its original length, it gathers up the seam, causing the pucker, which cannot be immediately seen; and may be noticeable at a later stage.
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.
Straight stitches are stretch resistant, use less. thread, and they are the stitch type you will use most. often. Zigzag stitches are used when sewing stretchy.

- overlock machine.
- zigzag machine with stand.
The presser foot you are using is incorrect. - Attach the presser foot that is correct for the type of stitch you want to sew. 2. The thread tension could be in correct.
The small stitches done back-and-forth makes the back stitch the strongest stitch among the basic stitches. Hence it can be used to sew strong seams by hand, without a sewing machine.
To sew two pieces of fabric together, a simple straight stitch is easiest. The example shows a straight line of stitches for clarity, but you can also sew two curved pieces of material together as well.
Can you use zigzag stitch for stretchy fabric?
Because of the structure of the stitches, zigzag allows the seam to stretch. Zigzag is a classic for sewing stretch fabrics on a home machine, and if that's the only stretch stitch your machine offers, it's a great option, but it is not necessarily the best option.
A universal needle can work well on many stretch and woven fabrics. Use a classic zigzag stitch for construction with a stitch setting of 2 length and 2.5 width. This stitch is ideal as it stretches along with the fabric, creating flexible seams – very helpful when getting in and out of your garments.
The Straight Stretch Stitch can be used to reinforce seams of sportswear in stretch and non-stretch fabrics, and for curved seams which take a lot of strain. This stitch is stronger than regular straight stitch because it locks three times – forward, backward and forward again.
The running stitch is the most basic and most commonly used stitch, in which the needle and thread simply pass over and under two pieces of fabric. It's exactly the same as a basting stitch, except it is sewn more tightly to create a secure and permanent bind.
It looks like a lightning bolt, and it works kind of like a zig-zag, except the needle goes back a little bit to overlap the previous stitch. This means that the stretch stitch can look more like a straight line. You might see this stitch called a lightning stitch.
