I went to a quilt store and bought a rather substantial stash. The owner (who knew me privately) said to me: "Please tell me you are not buying ALL THAT for the same project." I said that it was. She then asked:"What will you call it - Nightmare on Elm Street?" I told her that I would bring the finished piece in and that she WOULD EAT HER WORDS.
I made the quilt EXACTLY as I had envisioned, and took it in to her. She made a real sourpuss puckered face and said that it turned out differently than she had thought.
SO, if you have the design in your mind, then you go ahead and finish it. If for no other reason than to prove to YOURSELF that YOU WERE RIGHT in your choice.
I'm pretty sure that DH would not have made a comment, had he known that he could knock you off center.
