I would continue with the rows you have not done with the walking foot and rip out the other ones while watching TV! Just another thought. I have not stitched diagonally until after I have done the horizontal and vertical rows. Could the distortion be because of the bias? Welcome to the board. You will learn so much. The people are wonderful here. So knowledgable!
