What do you do if your bobbin thread won’t catch?
Your Needle Is Not Inserted Correctly
If your needle is not being held in all the way, it won’t be in the right place to grab your bobbin thread. Make sure your needle is inserted all the way up and tightened as much as possible. Also, make sure not to insert your needle backward on your sewing machine.
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.
Why won’t my sewing machine needle go up and down?
A disengaged clutch, broken drive belt or internal drive gear failure can prevent the needle from moving. … If the needle won’t move with the clutch engaged, unplug the sewing machine and check the drive belt. Replace the drive belt if it’s broken.
