in glass. A scale of one inch to a
foot will do generally, but all difficult or doubtful combinations of
colour should be sketched larger--full size even--before you venture to
cut.

_Work should be kept flat by leading._

One of the main _artistic_ uses of the leadwork in a window is that, if
properly used, it keeps the work flat and in one plane, and allows far
more freedom in the conduct of your picture, permitting you to use a
degree of realism and fulness of treatment greater than you could do
without it. Work may be done, where this limitation is properly accepted
and used, which would look vulgar without it; and on the other hand, the
most Byzantine rigidity may be made to look vulgar if the lead line is
misused. I have seen glass of this kind where the work was all on one
plane, and where the artist had so far grasped proper principles as to
use thick leads, but had _curved these leads in and out across the folds
of the drapery as if they followed its ridges and hollows_--the thing
becoming, with all its good-will to accept limitations, almost more
vulgar than the discredited "Munich-glass" of a few years ago, which
hated and disguised the lead lines.

_You must step back to look at your work as often and as far as you
can._

_Respect your bars and lead lines, and let them be strong and many._

_Every bit of glass in a window should look "cared for."_

If there is a lot of blank space that you "don't know how to fill," be
sure your design has been too narrowly and frugally conceived. I do not
mean to say that there may not be spaces, and even large spaces, of
plain quarry-glazing, upon which your subject with its surrounding
ornament may be planted down, as a rich thing upon a plain thing. I am
thinking rather of a case where you meet with some sudden lapse or gap
in the subject itself or in its ornamental surroundings. This is apt
specially to occur where it is one which leads rather to pictorial
treatment, and where, unless you have "canopy" or "tabernacle" work, as
it is called, surrounding and framing everything, you find yourself at a
loss how to fill the space above or below.

Very little can be said by way of general rule about this; each case
must be decided on its merits, and we cannot speak without knowing them.
But two things may be said: First, that it is well to be perfectly bold
(as long as you are perfectly sincere), and not be afraid, merely
because they are unusual, of things that you r
