I'm also retired and my sewing room is my retreat. My husband is gone in the evenings and I'm alone and that's when I do my quilting. I only work on one project at a time to completion. That works for me. My personality requires me to have order. No right or wrong..personal choice. Sometimes I sew the whole evening away and other days not so much. I am so thankful for this hobby and that I control my time now that it's mine to control. My sister who is my mentor told me when I began that there are no rules. Just do what works for you!!!!!
