We all learn from our mistakes and depending on our level of quilting even professional quilters make mistakes,that is part of life. We learn from our mistakes. What I don't agree with is the way it is said sometimes,it can make or break someones confidence. I remember going to a quilt show and told an older lady that I was a quilter too (beginner) but I sew my pieces together by machine she said that's not quilting I was so hurt I almost cried then someone said to me it's a new world out there and she only sees her way as the right way if I would of listened to her I would not be quilting today but here I am and I still make mistakes. Be careful how you give advice, your way may not be everyone's way and there are no quilting police out there. No one is perfect. Give credit for them trying so hard they will improve as time goes on we all started as beginners. Your color scheme may not be theirs. Everyone has an opinion and is entitled to their own opinion, but don't try to make yours the right one. .....Remember the poem Quilt of Holes it was a beautiful. We all see things in a different light.
