The bottom canvas of a round-cornered cushion for a gig should be cut out by the top pattern of the driving-box, sufficient being allowed for turnings, etc. To get the shape of the corner, bend a piece of stiff paper or floorcloth round the edge of the box from the centre of the seat at the back to the sham door at the front, marking round both top and bottom edges, and cutting out the material to whatever depth of cushion is required. The side and front also are governed by the size and sail of the seat; the top is cut to the pattern of the bottom canvas, allowance being made for the sail out at back and side, and for the fulness for the pleats and seams. In making up the cushion, seaming cord is usually worked into the seams, the cushion being made inside out, a space being left at the back bottom edge for stuffing. To do this, turn the cushion right side out, and fill it with whatever material is used, working it well to the front and sides to preserve the shape. Then sew up the back and tuft it down equal, and tie the bottom buttons securely with a double slip knot to prevent them becoming loose.
