I work 50 hours a week with a minimal commute and dont have kids. Im lucky enough that I have a housekeeper that comes in twice a month to clean the house so I only have to "pick up".
Since my hubby works Saturdays, I usually quilt all day (10-12 hours) Saturday or Sunday and one or two evenings a week for a few hours while I watch TV. I do have a dedicated sewing room that I will post a pic of one day after I finish the quilt I am working on.
