I would hesitate to advise anyone of an error they've made for fear I may be wrong -- I'm such a rank amateur when it comes to making quilts. I subscribe to pursuing excellence in any hobby one participates, to knowing in my heart I've done the very best I could (with the abilities I have). I try very hard NOT to stress over anything --- stress is not really good for us. There's not one of us on the face of this earth who is "perfect" in everything we do. So, I say strive for the very best you can do, and leave it alone. If someone asks for an opinion, give it, kindly, and constructively. We cannot live without occasionally offending someone, even if it's not our intent. I know I make a lot of mistakes -- but I'm learning!
