I am sorry to hear that people have been rude to you. This is something I have not found among quilters but I live in a small community. Our group is a loose knit group of quilters. We don't have any rules or dues. When we do charity projects, everyone makes a contribution. We enjoy sharing whatever we are working on and seek advice from one another when we need it. We are not all at the same stage in our quilting journey. We know that we are not perfect and do not expect perfection in others. There is never a legitimate time to be rude. Even the best quilters make mistakes. Hopefully we can learn from them and become better quilters. Most of us will never be professionals but that doesn't mean we can't make beautiful quilts.
