You asked: Why is my zigzag stitch loose?

Why is my zig zag stitch loose?

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. It may show at the sides of the stitch and the fabric is slightly raised or bunched. If you see this, slacken off the tension slightly (perhaps to between 3 and 4).

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.

What causes a loose stitch?

Why does my needle keep Unthreading?

Your Sewing Machine Thread Tension Could Be Off

One of the most common issues leading to a needle that keeps unthreading is a sewing machine with the wrong thread tension in place. Thread tension at the top that’s either too high or too low can result in this issue.

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.

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.

Can you zigzag with a walking foot?

Yes, you can use your walking foot for more than straight stitching. A zig-zag stitch should be just fine because all the movement in the stitch pattern is forward. In fact many of the decorative stitches on your sewing machine are just fine to use with your even feed foot installed.

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.
