I think people who like to quilt are satisfying their need to create, whatever that may be. I'm just finishing a T-shirt quilt and feel it may be my last. It was a challenge and if it were not for a grandchild I don't think I would have tackled it. I now do mostly small quilt projects as have all the quilts I want - either to gift or for myself. Some people have a passion for cooking, painting, embroidery, crewel, puzzles, reading, flowers, or whatever else they enjoy. Just do what you want, especially as you get older.
