I do the ceiling and walls once a month and the floors once a week and dust whenever. One time I let the dusting go and wrote on a table Martha Stewart Doesn't Live Here. My GD got a big charge out of that. Some days I just want to be creative and learn new quilting blocks or finish a project and I could care less about the house. As long as we are healthy and happy it will be fine. Always another day to clean as long as I don't let things go to long and make it harder on myself.
