Why are my sewing stitches coming undone?
The machine is not correctly threaded
If the machine is threaded wrong, not only does it make the thread breaks easier, but is also more likely to create loose stitches. Check the threading to see if the thread has passed through the entire thread guides, the take-up lever and the eye of the needle.
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.
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 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.
Can you reverse stitch with a walking foot?
When not to use a walking foot.
REVERSE SEWING: The foot isn’t designed for use in reverse. foot assists in forward movement and won’t allow the fabric to move side to side. SOME DECORATIVE STITCHES: Wide decorative stitches require side to side fabric motion, which is inhibited by the walking foot.
Probable Causes: – Top or bobbin thread is not set correctly. – Make sure that the bobbin was threaded properly in the shuttle race. …
