I'm so sorry! I can't even imagine how you have chastised yourself over this. I love the reactions from our members regarding your back. I agree with all of them and maybe you will be able to think of your (hand-quilted masterpiece) as two separate quilts. Each with their own placement. I have not used a directional backing yet but have had seam lines that looked horribly wonky. Can not seem to get them centered and straight. Finally, had to accept my abilities and move forward. I commend all of you hand quilters. I believe it is amazing.
