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.
Why do my stitches look weird?
Here’s an example of what straight stitches look like with varying tensions. 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.
Why is my stitch loose?
On this machine the stitch length can vary from 0–4mm. This indicates that the tension is too loose on both the bobbin and needle thread, the machine has not been threaded correctly, or the thread has not been placed properly between the tension mechanism.
Why is my top thread looping?
Looping on top generally means the needle tension is too loose. Change your needle. The golden rule for needle selection is to use the smallest sharpest needle that can carry the thread through the fabric without damage to the thread, fabric, or needle. Change your thread.
Why does my top stitch look wrong?
Poor thread tension on a machine-sewn seam can result in an unstable seam, puckering, or just plain unattractive stitching. Perfect machine stitches interlock smoothly and look the same on both sides of the fabric. If you see small loops on the right or wrong side, the thread tension isn’t correct.
What stitch length and tension should I use?
What stitch length should I use?
|What is the best stitch for:||Suggested Stitch Length (mm)||Stitches Per Inch|
|Standard Stitch Length||2.5 – 3.0||8 – 10|
|Basting stitch||5.0 – 7.0||4 – 5|
|Stay-stitching||1.5 – 2.0||12 – 8|
|Top-stitching – light/medium weight||3.0 – 3.5||7 – 8|
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.
What should sewing machine stitches look like?
Machine stitches should look the same on both sides of the seam when you sew patchwork pieces together or when you. … The little knot formed between stitches (at each indentation between them) should be invisible, buried in the layers.
What is the best solution if stitches loop?
Causes of Stitches Looping
Looped stitches are usually caused by improper tension. If the loop is on the upper side, it may be corrected by loosening the top tension or by tightening the lower tension. If the loop is on the under side, it is usually best corrected by adjusting the upper tension.
