I'm sorry you weren't made to feel part of the groups. To me it doesn't matter your age, we all started at the same place... the beginning, no matter our age. In time you will be a seasoned quilter and more than willing to help the younger crowd of new quilters. DON'T GIVE UP!!!!!!
Many people can't even sew on a button and sewing/quilting is a great skill to learn. We (borad members) will help you all we can, just know you are welcome HERE and will not be judged.
BTW, would love to see some of your quilts!
