Transfer the main outlines of
the design on a piece of tracing paper, then place the blank
side of the paper against the piece of glass; back it with cardboard,
and secure the whole with elastic bands or paper clips to prevent
movement. The design should now be seen reversed, as in a mirror.
Thoroughly clean the front of
the glass to remove any fingerprints of greasy patches. With
Indian ink, black out all of the background, leaving the parts
that will show the foil clear. When thoroughly dry, apply a second
coat of ink. After allowing that coat to dry, the paper and card
may be removed. Cut the foil roughly to the shapes required,
and using photographic paste, place the pieces in their respective
positions on the inked side of the glass, and smooth the foil
gently. If the foil slightly overlaps the ink, it does not matter;
it will not show.
Build the picture up from the
center to the outside, and finish one color before starting on
the next. Cover the finished work with paper, and smooth gently
but thoroughly all over to ensure that every part is firmly fixed.
When dry, coat with clear varnish, and leave to set.
Place the backing cardboard
into position again, not forgetting to fix any hangers if they
are required, and then bind the edges with passe partout.
Even the smallest piece of foil
left over will have a future use, and every bit however small,
should be saved.
In the case of buildings, remember
that light windows should be shown in silver or gold foil, an
skies should of course be blue, grass green, etc.
