Double-pointed Tack.
When you take canvases out-doors to work, you will find it useful to strap two together, face inwards, with a double-pointed tack like this in each corner to keep them apart. You will not have any trouble with the fresh paint, as each canvas will then protect the other. You can pack freshly painted canvases for shipping in the same way.
Panels.—For small pictures panels are very useful, and when great detail is desirable, and fine, smooth work would make an accidental tear impossible to mend well, they are most valuable. They are made of mahogany and oak generally.
Panels are useful, too, for sketching, as you can easily pack them. They are light, and the sun does not shine through the backs. You can get them for about the same cost as canvas for small sizes, which are what you would be likely to use, and they are often more convenient, particularly for use in the sketch-box.
CHAPTER III
EASELS
The important thing in an easel is that it should be steady and firm; that it should hold the canvas without trembling, and so that it will not fall as you paint out towards the edges. You often paint with a heavy hand, and you must not have to hold on to your picture with one hand and paint with the other. Nothing is more annoying than a poor easel, and nothing will give you more solid satisfaction, than the result of a little generosity in paying for a good one. The ideal thing for the studio is, of course, the great "screw easel," which is heavy, safe, convenient, and expensive. We would like to have one, but we can't afford it, so we won't speak of it. The next best thing is an ordinary easel which doesn't cost a great deal, but which is firm and solid and practical. Don't get one of the various three-legged folding easels which cost about seventy-five cents or a dollar. They tumble down too often and too easily. The wear and tear on the temper they cause is more than they are worth. It is true that they fold up out of the way. But they fold up when you don't expect them to; and you ought to be able to afford room enough for an easel anyway, if you paint at all.
