How do you adjust the tension on a zig zag stitch?

What should the tension be 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.

How do I stop Zig Zag puckering?

The tunnel is easily seen on the top row of zig-zag stitches. While not as noticeable in the picture, the fabric puckered on the last row, too. Solution: Use a stabilizer for support or sew a heavier weight fabric.

Why is the stitching loose 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.

How do I know if my bobbin tension is correct?

The thread should unwind just slightly and the bobbin case should drop an inch or two. If the thread unwinds without resistance and the case slips to the floor, your bobbin tension is too loose. If the bobbin case doesn’t budge, your bobbin tension is too tight.

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 zigzag stitch look weird?

Zigzag Stitch

The stitch on the left had too much tension, so it pulled the fibers of the fabric together and caused a small lump between zigzag points. The stitch on the far right is too loose from point to point, causing a bit of shadowing under the stitch itself.

Why is my zig zag stitch bunching up?

You will also need to be a little careful with lighter fabrics, as zigzag stitches can cause them to bunch up underneath. If you’re finding that is the case, look or the version of the stitch that is dotted. This created a zigzag that has three stitches instead of two, getting rid of the bunching issue in the process.

Why is my zig zag stitch uneven?

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.

How do you adjust top stitch tension?

To increase your top tension if it’s too loose, turn your knob so that the numbers are increasing. Try ½ to 1 number higher, then test the stitches on a piece of scrap fabric. Continue until it looks even on both sides and you can no longer see the bobbin thread on the right side of the fabric.

How do I get the right tension in my threads?

Pull some thread off the spool in the machine and cut it close to the spool. Tie two or three overhand knots in the thread, and be sure they are tight. Unthread the needle, and pull the knotted thread through the tension disks down by the needle. The tiny knots often catch bits of lint in the tension discs.

How do you adjust thread tension?

You should see a small screw on the flat/closed side of the bobbin case. Turning the screw a tiny bit counterclockwise will loosen the bobbin tension; turning it clockwise will tighten the tension.
