dressing the frame
, is an operation which requires considerable care. The frame itself, especially for a large piece of work, should be substantially made; otherwise the stress upon it will be apt to warp it, and drag the canvas. If this occurs to any extent, the injury can never be repaired.
1908. To Frame Canvas
After herringboning the raw edges of the canvas, sew them,
by
the thread, to the webbing of the frame,—that is, to the top and bottom. Then stretch the ends till the canvas is extended to its utmost length, put in the pegs, and brace the sides with fine twine. If the canvas is too long for the frame, and any part has to be rolled over the end, let the wood be first covered with a few thicknesses of silver paper.
1909. Design on Cloth
Sometimes, to save the trouble of grounding, a design is worked on cloth, over which canvas is laid. Whenever this is the case, the cloth must be carefully damped, to remove the gloss, before it is put into the frame. Then, as cloth will always stretch much more than canvas, it must be cut a little smaller both ways. The raw edges of the cloth should be turned in, and tacked to the canvas before they are framed. Some people withdraw the threads of canvas after the work is done; but it has a much richer effect if the threads of canvas are cut close to the outer stitches; and if there are any small spaces in the pattern, where the ground should be seen, they may be worked in wool of the colour of the ground.
