Step 11: If you can, lower your cutting blade. If not, carefully do the next step.
Yes! I highly suggest lowering your cutting blade when you do the turn. I don't worry about the beginning because I will go over those stitches. I make sure that I sew close to the edge at the start, and I lower my blade for the finish. That sample was done after quite a bit of practice as well. Yes, practice will ALWAYS help.
