The bobbin tension could definitely be loose. At the moment, the template plastic is doing the trick and my time to complete this project is down to 28 hours. When the boat is out of the driveway and on its way to its permanent home, I can take time to mess with the tension. In fact, I hope to find someone to work on my sewing machine and figure out why it sticks at a certain point. Thank you so much, all of you, for the helpful tips and advice!
