Next we might note the arm. Turn up the sleeve if the elbow is hidden. Hinges or joints are very important, and the more we see of them the better we shall understand the working of the human frame. Kathleen has a thin but shapely little arm, the upper surface of which is gently rounded and the lower straighter and firmer because of the bones beneath. The thumb rises to a point, and the fingers fall outward more or less in the shape of a fan. The position of this hand is very simple. But ten to one, if the pose had been left to Kathleen's choice, she has clasped her fingers tightly together, for that is a very natural thing to do with an unoccupied pair of hands. And clasped hands are very difficult to draw. One invariably makes them far too large. It is not easy to fit four fingers and a thumb on that small thing called a palm until we have gained experience.
Having arrived at the arms and hands we continue with the lower limbs, tucking in the skirt (folds can be very misleading) to show the upper part of the thigh. The square angle resting upon the seat of the stool is sharply defined. The knee is more or less hidden, but ask Kathleen to touch the knees where they bend, or hold the skirt tightly across the knees, and mark it well in your mind, or on your paper, because from there we trace the lower part of the leg.
Now we follow the curve of the leg, noticing the flat surface of the front part compared with the calf. Your Kathleen may not have as much calf as my Kathleen. Girls have very often the thinnest of arms and legs, and it is a common mistake to give too much flesh. Next we draw the feet. The boat-shape of the foot seen in profile (or sideways) is broken up with the strap, which marks also the thickest part of the foot, the instep. From that curve it descends steeply to the root of the toes or the curve of the shoe proper. Stout, sensible shoes has Kathleen, and the sole and heel are easily traced, marked as they are with the shadows of the leather.
Lastly, note the most important shadows and folds; also the hair, neckband, cuffs, or double-back sleeves—just so far as your interest carries you, but no further.
