Next drive a clout nail a little below and in the middle of the fold, and then other ones on each side, at intervals of four inches, as before, some one else helping you to keep the fold even and parallel to the top line of clouts while the tacking is being carried on. All that remains to be done is to tack down the two sides, straining out from the center towards each side. If there be a seam in the part of the canvas just lifted up, get it horizontal by means of the chalk line and nails, as before explained, which would also serve to regulate the tacking at the bottom. Now size and prime the new surface in the same manner as before, using the size and priming hot, and the whole of the canvas will present a uniform appearance.
