I was able to switch almost every step to my left hand except sewing the pleats. For the pleats, I needed to use my left hand to hold the fabric/keep the proper tension while I completed the hidden stitches with my right hand. I tried to switch hands, but I found that I kept the tension better with my dominant left hand, and the angle of the stitching felt better with the right hand.

Sorry 'bout the hijack, but Turpin asked for me by name. We now return you to your regularly scheduled thread.
