What is staggered stitching?
The stagger stitch reduces the thread build-up along the book spine by alternating the thread position. The stagger stitch reduces the thread build-up along the book spine by alternating the thread position. It is especially useful when sewing thick books printed on thin paper.
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 I know if my bobbin tension is correct?
The thread should unwind just slightly and the bobbin case should drop an inch or two. If the thread unwinds without resistance and the case slips to the floor, your bobbin tension is too loose. If the bobbin case doesn’t budge, your bobbin tension is too tight.
What are the characteristics of a good stitches?

- The length of stitch is proportioned to the texture of the fabric.
- The stitches are the same in length.
- The stitches appear the same on both right and wrong sides of the fabric.

What is the remedies of seams pucker?
Solution. Reduce the tension applied to the thread while it is being wound onto the lock stitch bobbin. Set the needle thread tension to be as light as possible while achieving a balanced stitch at the same time. This will reduce the amount of puckering while the thread is stretched and improve the sewability.
