I don't think it is your age. It's been a long time since I was a young quilter, but I still feel like an outsider sometimes. It seems like forming new friendships gets harder as time goes on. I don't have a lot of quilting friends, 2 to be exact, but that doesn't stop me. I don't mind quilting alone at home, so that's what I do. Keep it up and enjoy the journey.
