FIG. 35
All other twines are fastened and tied in practically the same manner. However, care must be exercised that the springs are not drawn down lower with successive strands of twine, or an uneven strain and wear will result. The last twine should be tied to all others crossing at the spring centers, to prevent twine wearing at these points. A study of Fig. [34] should make clear any doubtful point.
Tack a piece of 10 or 12-oz. burlap on the top edge of the frame with 4-oz. tacks, folding the edges over as they are being tacked. Fasten it just tight enough to insure smoothness, avoiding pulling the springs down lower. As previously stated all spring reaction strain should fall on the twine exclusively. Sew the burlap to the springs with a curved needle and stitching twine. This keeps the burlap in position, prevents wearing, and helps to unify the seat.
Place the stuffing. Work over about 5 pounds of tow, and work it down and out over the seat until it extends about 3 inches beyond the frame as shown to the left of Fig. [35]. Be careful to keep the tow even at all times, especially at the edges.
FIG. 36
Place a piece of light burlap, 6 or 8-oz. weight over the tow. It should be large enough to be slip-tacked on the sides of the frame. Stitch thru the two layers of burlap and the tow with a 12-inch double-pointed needle. The row of stitching should come just outside the edge of the springs. Each stitch should be about 3 inches long, and it is formed by passing the needle up and down thru the burlap. After all four sides have been stitched pull the twine tight. Begin at the first stitch and pull each taut in succession. Finally take a few stitches thru the center of the seat at irregular intervals, thus making the seat firm and compact. Do not stitch around the loose coils of the springs.
