I am getting better at it! I found an Australian blog and a lady there has a very good way with the 201. I sat down, threaded the machine up with a light to medium weight cotton thread. At first I had the same issues with loops galore and thread breaking, but after a bit of tuning the tension knob and getting into the feel of the speed on the machine and the movements of my hands it goes much smoother. I have almost perfect stitches, a couple of places it slips of I go too fast; then loops appear or it skips stitches in a bend. It's all in the speed and movement.
I have the feed dogs lowered, pretty tight upper tension (closer to 7), and when I aim for low speed and have fairly small stitches it stitches fine. I need more practice. How does it all come together on a 15?
