Why does my sewing machine gather the material?
Friction between layers of materials
When sewing, the feed dog grips the fabric to help the material pass through the machine. … You need to re-sew the affected parts, or use a suitable presser foot to lower friction. Friction between layers of fabric built up during sewing may cause seam gathering/puckering.
Why is my sewing machine gathering thread underneath?
Your Thread Tension Is Too Tight
Sewing machine manufacturers suggest that you don’t mess with your bobbin thread tension too much, but you should adjust your upper thread tension if you keep getting bunched up thread underneath your fabric. If your tension is too tight, it can pull your thread and break it.
Why is the back of my sewing messy?
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.
What tension should I use for cotton?
Cotton requires a moderate tension setting, usually between three and four.
What is the common cause of puckering of seams breaking of needles and threads?
Causes of Puckered Seams
Puckered threads across seams are due to a blunt needle or too large a needle. Stitches are too short for synthetic and easy care fabrics. Using a plate with a wide needle hole may cause straight seams to pucker. Upper thread and bobbin threads are of a different size and/or type.
