I am retired so my time is my own but for what it's worth I really admire the moms with kids at home and those of us who still work 40 hours a week. You guys are awesome to get anything done at all.
After teaching all day, the best I did was "think" about my projects.
My quilting time is determined by my self-imposed schedules. If there are quilts that need to be completed by a certain time, I really can get into gear.
Usually, though, I have a hand project to do while watching TV with my honey. (my sewing room IS the living room so the machine makes too much noise while watching TV for him....he is the greatest, very understanding of the projects, thread and the like laying around almost everywhere!
