T.
Tracery Window.—The general method of modelling windows of this description is very simple, but the practice difficult. First, paper upon which you intend to cut out any tracery, must be pressed closer together than that used for ordinary work, so as to afford more assistance to the knife when cutting on the splay. Having drawn the design of your window, proceed to cut out all the interstices with knife No. 3; then splay down from the nosing with knives Nos. 1 and 2, as each may be found useful, cutting through with one stroke, or rather with a succession of short strokes right through on the slant, boldly and without leaving a jagged edge; afterwards smooth your work with ivory or agate. You had better place the pieces that came from between the mullions while cutting the splay, in their places again between the mullions, to offer resistance to the knife and prevent them bending. The eyes may be successfully formed by packing-needles of diamond shape, fixed in a handle.
