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 much thread do you put on a bobbin?
Unwind about 18″ or so of thread and bring it around the backside of the bobbin winder tension disc, wind it around the tension disc one time. Some machines might have a thread guide before this step- if yours does, don’t skip it! Be sure to place your thread through all the thread guides on your machine.
What is a bobbin thread?
When sewing with a machine, the thread wound around the bobbin links with the upper needle thread to form the bottom part of a stitch. Typically used in machine embroidery, quilting, and sewing fine fabrics, bobbin thread is lightweight and strong, adding little bulk while still securing stitches.
Why isn’t my bobbin thread coming up?
First, make sure the bobbin-winding spindle (located on top of your machine) has been pushed back to the left for sewing. If it is not in the correct position, the needle will not go down and pick-up your bobbin thread. … If the timing is out, the needle thread is not meeting the bobbin thread in time to form a stitch.
