It is generally agreed that in learning fundamental skills in clothes making, it is more advisable and efficient to leave the pupil to make plans of their own for something useful in actual life and enjoy the process of making it, than to make him or her sew or knit for a long time without any other object than merely giving lessons in sewing or knitting. In order to give theoretical confirmation to this general idea, fatigue brought on in the course af sewing and knitting work was measured with the Flicker Value Measuring Apparatus. Subjects were chosen from among those who are fond of and well-experienced in sewing, those who don't care for sewing and are inexperienced in it, those who have neither a liking nor a dislike for sewing, and also those who are fond of and well-experienced in knitting. Fatigue was then measured both in the case of making a table wiper and in the case of mere needle handling drill, using the same material and sewing kit, and under the same working conditions. Every subject group showed less fatigue in the case of making a table wiper than in mere needle handling drill. Again, lower degree of fatigue was registered when knitting was done for a definite purpose of making a table centerpiece than when done for no particular purpose. It was concluded from the present fatigue measuring experiments that greater efficiency can be achieved by encouraging the pupil to learn the way of sewing or knitting with something concrete in mind than by drilling him in the mere skill of sewing or knitting.
