Personally I believe that not everyone is on an equal level and when someone is trying to create something who are we to tell them they are doing it wrong. If it makes them and those they are around happy who are we to think that we should take that away from them. I will venture to say that none of us started out perfect it was a long process of trial and error. But I can guarantee you that if someone had torn down what I made the first time " I probably wouldn't have made another" since then I have won a number of first place ribbons and I have sold hundreds of quilts in my shop so in answer to your question No I don't think it is our right to act as a teacher and grade what they do. Complimenting someone for what they have done will make them try again and again. Just my humble opinion
