Edward, you are doing fine. Take your time. Just remember, once the pattern is removed, there will be no lines for anybody to see. You can make a lot of mistakes and nobody will ever know. I'm in the same boat as you as far as experience goes. I am doing a wall plaque that will be a gift and I'm really taking my time and trying my best not to make a mistake that's really obvious. Keep up the good work and post your finished project.
