Well-planed modeling boards, twelve by fourteen inch es, are very useful for flat work; however, school slates, or the ordinary roofing tiles may serve the same purpose. If the work is to be carried on in the schoolroom, the desks may be protected with pieces of oilcloth the size of a modeling board. The work may be built upon this, if desired. The same piece of cloth may be wrapped about the unfinished work, thus keeping it in good condition for the next lesso/n./ A few wooden tools made by anyone handy with a knife will be needed, but the most useful of all tools is that supplied by nature — the thumb. In the earlier stages of a model, the fingers and thumb will give the general form desired, and the tool will only be needed in refining the work later on.
