From Singer Sewing Book that was published in 1949.
When you sew, make yourself as attractive as possible. Go through a beauty ritual of orderliness. Have on a clean dress. Be sure your hands are clean, fingernails smooth --a nail file and pumice will help. Always avoid hangnails. Keep a little bag full of French chalk near your sewing machine where you can pick it up and dust your fingers at intervals. This not only absorbs the moisture on your fingers, but helps to keep your work clean. Have your hair in order, powder and lipstick put on with care. Looking attractive is a very important part of sewing, because if you are making something for yourself, you will try it on at intervals in front of your mirror, and you can hope for better results when you look your best.
Again, sewing must be approached with the idea that you are going to enjoy it, and if you are constantly fearful that a visitor will drop in or your husband come home and you will not look neatly put together, you will not enjoy your sewing as you should. Therefore, “spruce up” at the beginning so that you are free to enjoy every part of any sewing you do.
Can you believe it? I'd hate for them to know that sometimes when I know all I'm gonna do is sew all day long I stay in my P.J.'s and don't even put on my makeup!!
