So today I sat at my old kenmore because I wanted to make masks for the neighbors to do something nice. But my needle kept dropping the thread and not sewing at all. I spent 2 hours trying to fix it but nothing worked. So I switched to my newer singer to do the job. Got about halfway through one and the needle broke. I changed the needle to a brand new one that was the exact same size and it started doing the same thing as the kenmore! I disassembled the bobbin casing twice to make sure it was clear and adjusted the tension. I tried a test piece and it sewed fine. Great, I thought. Its working now. Began sewing on my project and it slipped the needle. I dont get it. I'm so frustrated I just decided to walk away from it today. I have other things to do and after 5 hours of sewing and repairing I dont even want to look at my machines.
