For me, I feel a profound sadness when I finish a quilt. It's very hard to even explain. I want to avoid that sadness, so I prolong finishing. The sadness is there even if the quilt is the best and prettiest I have made. I have been known to simply drop the quilt on the floor after the last stitch on the binding is done. Why? Because all the planning and preparation was what got my juices flowing. I think it's like having a child grow up and not need his parents anymore. The end result may be what you had hoped it would be all those years, but it hurts to have the process over.
