The next members, Nos. 1, 3, 5, and 7, are formed, first by preparing the size and length on the square; secondly, by cutting off at any angle necessary to get as near to the mould as possible; and, lastly, forming the mould itself.
The manner of moulding being applicable to every description of either Italian or Gothic pattern, we proceed to describe it.
Procure from the comb-manufacturers some pieces of ivory of various sizes, and with different files, some round, some square, &c., file on one end of a square piece the reverse of the mould you require; smooth it well; and for greater power and convenience, fix it in a handle of wood.

Nos. 1, 2, 3, &c., &c., will be found generally available and useful in the formation of all kinds of mouldings, besides numbers of other shapes that will occur to the artist. The method of using the instrument is by indenting the pattern along the edge of the cardboard, guided by means of the straight-edge. The sharp arris left from the file upon the edge of the ivory mould, had better be slightly taken off, to prevent the paper being torn in its passage.
The circular pediment over windows (fig. 2, page [61]) must be modelled on the flat, and the moulding returned at the ends. When each member is finished, they must be gummed up and bent to the required curve, over a circle of cardboard or a cylinder of wood, separately. The panels that occur form thus: Cut as before directed for doors, the extreme size of the opening, and at the back place the successive sizes and thicknesses to form the mouldings, indented into hollows or worked to rounds, &c., &c., by means of one or more of the moulding tools; to be backed last of all.
Commence the preparation of the quoins (fig. 6, p. [61]) by cutting pieces the required thickness and width of both long and short quoins, and in long strips, with the height of each one marked up its length previously by the dividers.[[3]] Cut first the requisite splay at the edge of the quoin, along the whole length both sides. Cut where marked for height, and splay top and bottom. They are then finished, and may be at once fastened to the work.
