Welcome from NJ. I usually machine piece but do almost exclusively hand quilting. Enjoy the process - it's not a race.
That said, perhaps if you're having so much difficult with your machine it might be time for a new one?? I had an old White that just was not a great machine - 80's vintage. Ate fabric, tension always an issue, etc. I ultimately broke down and bought a computerized Viking. Best decision I ever made. It sews beautifully. I also have a couple of vintage machines that are great as well but the Viking is my 'go to' machine because of the features it has that were important to me.
