I do stop with the needle down, The problem is happening when I start up again and take that first stitch. It's getting better as I am learning to come forward and continue the line at a 5 o'clock or 7 o'clock angle but of course I strive for a seamless transition.
I like the angle idea.
In reality though my goal is to eventually learn to do smooth spirals and hearts and flowers and they all have curves.
