Take a circular piece of plush, 2 in. to Hin. larger in diameter than the frame, cut all round the edges to the depth of plush that will overlap the frame; lay the plush right side down on the table without creasing it, apply round the front of the frame a touch of glue, which must be strong and not watery. Then lay the frame on the plush, and strain it tight by pulling it with the hands; then by different stages apply the glue at the back and overlap the overhanging plush, taking 3 in. or 4 in. at a time (see A, Fig. 1). Press the plush into contact with the wood with a bone paper-knife or piece of wood. When completed and nicely set, with tailor's chalk draw a circle in the centre of the plush, then cut it out with scissors; leave a margin of l in. or 3/4 in., so as to overlap on the rebate of frame. To get the circle easily, a dinner plate may be employed as a guide. After cutting out the circle with scissors, cut the inner edge all round to the required depth. It requires great care not to cut too far, but just so that it will overlap and fit snug (see B, Fig. 2). Press it well into the rebate, a little at a time.
