There are numerous ways of preparing canvas for painting in oil, but most people prefer that which comes ready prepared by experienced manufacturers, as paintings executed upon such canvas will not crack or peel off, and can be had in different shades. Some of our readers, living at a distance from art stores, may wish to prepare their own canvas from linen, and thus economize in this direction. the method usually adopted is as follows: Procure a piece of good, strong, unbleached linen, the desired size, and see that it is evenly woven; the edges should be hemmed to prevent fraying out. It is then fastened to the stretcher, in the manner described in the foregoing paragraph. Key it up sufficient to tighten it fairly well. You now make a preparation of thin liquid glue, and spread it all over the linen, as evenly as possible. this must be allowed to dry thoroughly, when you then give it a coating of light gray paint, made by mixing silver white and a little ivory black, made quite thin by adding turpentine. This makes what is called the single primed canvas, and is preferred by many without any further preparation, and furnishes a very agreeable surface upon which to paint, the threads of the linen showing through. The smooth-finish canvas is the result of still another coat of paint, thinned this time with linseed oil instead of turpentine.
