So I was free motion quilting for about an hour. Then came back to it about two hours later to do the border. It started off great. Then I noticed it started skipping stitches. Then the thread started breaking periodically. After retreading the machine and I even changed the needle started sewing again. It didn't sound right so I stopped and underneath was was one big thread mess. Now why? Nothing changed The thread was the same the tension never changed I literally wanted to through the machine out the window
