The use of a lay figure will help you somewhat if you can get one which is true in proportion. It will not help you much in the finer modelling, but it will at least insure your structural lines being in the right place, and that is as much as you can hope for without the special study of the nude.
A lay figure is expensive, costing about three hundred dollars in this country. You will hardly be apt to aspire to a full-sized one, as only professional painters can afford to pay so much for accessories. But small wooden ones are within the means of most people, and will be found useful for the purpose I have mentioned, and one should be obtained.
When you have assured yourself, as far as you can by its use with and without special draperies, of the right action of your drawing, you must do your painting from the draped model.
The Model.—Never paint without nature before you. If you paint the figure, never paint without the model. For the sake of the study of it, it goes without saying that you can learn to paint the figure only by studying from the figure. But beyond that, for the sake of your picture, you can have no hope of doing good work without working from the actual object represented. The greatest masters have never done pictures "out of their heads." The compositions and æsthetic qualities came from their heads it is true, but they never worked these things out on canvas without the aid of nature. And the greater the master, the more humble was he in his dependence on nature for the truth of his facts.
Much more, then, the student needs to keep himself rigidly to the guidance of nature; and this he can only do by the constant use of the model.
One Figure or Many.—Whether you have one or more figures, the problem may be kept the same. The canvas must balance in mass and line and in color. When you decide to make a picture with several figures, study the composition first as if they were not figures, but groups of masses and line. Get the whole to balance and compose, then decide your color composition. Simplify rather than make complex. The more you have of number, the more you should consider them as parts of a whole. Keep the idea of grouping; combine the figures, rather than divide them. Have every figure in some logical relation to its group, and then the group in relation to the other parts. Don't string them out or spot them about. Study the spaces between as well as the spaces they occupy. And don't fill up these spaces with background objects. That will not bind the group together, but will separate it. Fill the spaces with air and with values—even more important!
All this arranged, paint each group and each figure as if it were one thing instead of many. As you treat the head, the body, the dress, and the chair as all parts of a whole in a single sitting figure, so treat the various heads, bodies, dresses, etc., in a group as parts of a whole, by studying always the relations of each to each. And then study to keep the different groups as parts of whole canvas in the same way.
Simplicity of Subject.—But do not be too ambitious in your attempts. Keep your subjects simple. Don't be in a hurry to paint many figures. Paint one figure well before you try several.
You will find plenty of scope for your knowledge and skill in single figures. Practise with sketches and compositions, if you will, in grouping several figures, and try to manage them so that the whole shall be simple in mass and effect; but do not attempt, as a student, without experience and skill in the painting of one figure, to paint pictures containing several. By the time you can really paint a single figure well, you can dispense with a manual of painting, and branch out as ambitiously as you please. In the meantime, everything that you have knowledge enough to express well, you can express with the single figure.
With the model, the background, the pose and occupation, the clothing and draperies, and whatever accessories may be natural to the thing as elements, it is possible to work out all the problems of line and mass and color. If a really fine thing cannot be made with one figure, more figures will only make it worse.
