Why won’t my needle catch the bobbin thread?
If it is not in the correct position, the needle will not go down and pick-up your bobbin thread. … Also, make sure your bobbin is in correctly (not backwards) and that the upper tension disks of your machine are threaded correctly. Make sure the presser foot is up when seating the thread through the upper tension.
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.
