A friend of mine has a couple of quilt tops her aunt made that are from the 40's. She has been planning on hand quilting them since they are hand pieced. She has 2 tops and 2 daughters. And she does not machine quilt. But it is better to have it completed by a family member since it was made by a family member. I would rather have a quilt that was pieced by my GGM quilted by a family member - even if it is done by machine, than hand quilted by a stranger.
I am not concerned about future value, only about the family side of it.
