It pays to quit for the day and start over after weighing all the options. I thought some for about ripping 4 layers of seams and decided that my first idea about moving the sashing on the third section to the other side was a better idea. It was not easy ripping out the one seam I might have pitched the whole thing if I had to take out 4 layers. What I did worked out well; I just had to trim off the batting and backing after I took out the sashing seam and I moved the batting and backing to the other side as well. I worried about the batting not being wide enough as it was already trimmed but because it was trimmed it was perfect I just join it with a wide zigzag stitch to the other edge. I always leave a generous amount to fold under on the backing so there was more than enough.
