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.
Why is my zig zag stitch not working?
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.
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.
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.
Is a zigzag stitch stronger than a straight stitch?
Though straight stitch is considered as the strongest stitch, zigzag is one of the most durable stitches. There are ways in which you can make the hold stronger. For instance, the triple zigzag is stronger compared to the ordinary zigzag ones.
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.
What does a good straight stitch look like?
When it’s just right, your stitch will look like the one in the middle. The one on the left is too tight, causing the fabric to pucker, while the one on the right is too loose, making the stitches loopy. Here’s the same stitch on the underside of the fabric.
What should I set my sewing machine to?
Most sewing is done in the 2.0 to 2.5 range. If you are foundation paper piecing, you may want to decrease your stitch length so that the paper tears away easier. Top stitching and quilting are usually done in the 3.0 to 3.5 range. Basting and gathering stitches are the longest, from 4.0 – 5.0.
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.
