Does blocking fix loose stitches?

Blocking can smooth out stitches, but it won’t magically fix uneven tension. If your knitting is “rowing out” or showing dramatic gauge differences between your knit and purl rows, you’ll need to adjust your knitting style.

Why is my first stitch loose?

If you’re getting a column of loose stitches along the edge of your knitting, it’s probably a sign that the tension is uneven between your end stitches and the center ones. … When you’re knitting the edge stitches, tug the working yarn a little tighter than you normally would to help keep the stitch a little smaller.

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 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).

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.

How do you tighten thread tension?

Changing Bobbin 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.
