Misery loves company.... Didn't you know that? I would have simply smiled and told him I wasn't in this world to live up to his expectations and to wait until someone asked for his opinion. I am a very peaceful person, but, he had no right to say anything to you. Who did he think he was... the quilt police?
Whew .... I am so glad I got that off my chest. I love your quilt. It is a masterpiece and any person who quilts knows what kind of work it took to make such a beauty. Forget that crabby old man, he doesn't know anything.
