Yes, From the top. Also I don't see any tension on the thread going into the tensioner. That doesn't seem right. The thread that's balling up looks like needle thread, not bobbin thread, right? If so it's probably a tensioning issue.
I realize this is a Singer and not an LS1. But on the LS1, the thread going to the tensioner doesn't just pass through the chrome bar above the tensioner, it wraps around it one complete turn and then down into the tensioner. You definitely need the manufactures threading directions to get this right.
