the expense, is not found to answer), is to prepare the formula for the
group intended to be painted. Get a piece of tracing or silver paper the
size of the cushion, mat, or screen you wish to paint, then lay it carefully
upon the group you wish to copy, and trace through. Should the paper
slip, the formula will be incorrect ; it will be therefore well to use weights
to keep all flat. Having traced your flowers, remove the thin paper,
and, laying it on a piece of cartridge-paper the same size, go over the
pencil-marks by pricking them out with a fine needle, inserted in a cedar
stick. Now that you have your whole pattern pricked out clearly upon
a stiff paper, take eight or nine more pieces of cartridge-paper, of the
same size as the first, and laying them one by one, in turn, under the
pricked pattern, shake a little powdered indigo over, and then rub with
a roll of list or any soft material. The indigo, falling through the
punctures, will leave the pattern in blue spots on the sheet of paper
beneath ; then proceed in like manner with the remaining formulas until
you have the self-same pattern, neatly traced in blue dots, on them all.
Next, with a sharp penknife, you must cut out the leaves, petals, and
calices of the group, taking care to cut only a few on each formula, and
those not too near together, lest there should not be suflicient room to rub
between the spaces, and that, for instance, the green tint intended for
the leaf should intrude on the azure or crimson of the nearest convolvulus ;
for in this sort of work erasure is impossible.
The following diagrams will show how the formulas should be cut, so
as to leave proper spaces. The shading denotes the parts cut out.
Some leaves may be cut out in two halves, as the large ones in the
pattern ; others all in one, as the small leaf; but it is chiefly a matter of
taste. The large leaves should, however, generally be divided. In cach
formula there should be two guides—one on the top of the left-hand side,
the other at the bottom of the right-hand corner—to enable the formulas
always to be placed on the same spot in the velvet. For instance, as in
formula 2, A and B are the two guides, and are parts cut out, in formula
2, of leaves, the whole of which were cut out in No. 1; and therefore,
after No. 1 is painted, and No. 2 applied, the ends of the painted leaves
will show through, if No. 2 be put on straight; if, when once right, the
formula is kept down with weights at the corners, it cannot fail to match
at all points. Care should, however, be taken never to put paint on the
guides, as it would necessarily leave an abrupt line in the centre of the
leaf. While cutting out the formulas, it isa good plan to mark with a
