Advice from a Singer Sewing Manual from 1949:
Prepare yourself mentally for sewing. Think about what you are going to do. . . never approach sewing with a sigh or lackadaisically. Good results are difficult when indifference predominates. Never try to sew with a sink full of dirty dishes or beds unmade. When there are urgent housekeeping chores, do these first so your mind is free to enjoy your sewing. . .When you sew, make yourself as attractive as possible. Put on a clean dress. Keep a little bag full of French chalk near your sewing machine to dust your fingers at intervals. Have your hair in order, powder and lipstick put on . . . If you are constantly fearful that a visitor will drop in or your husband will come home and you will not look neatly put together, you will not enjoy your sewing as you should. . .
