The lines
for copper foil and lead cartoons need to be of different sizes. Only a small width is required between glass
pieces in copper foil. This allowance is
for the two thicknesses of foil and a space for the solder to run through from front
side to the back side. In leaded glass a
wider line is needed to allow for the width of the heart of the came.
On cartoons
for different methods, draw the lines in the
appropriate width. For copper foil this
width is ca. 0.8mm. This can be
accomplished with a ball point pen or fine felt tip.
For leaded glass panels, a thicker line
of ca. 1.6mm is required. A bullet tipped felt pen is usually appropriate, if
it is not worn down at all.
A cartoon for fused glass should use the
finest line possible, as the glass pieces will be in direct contact (ideally) with
each other. As in copper foil, a ball
point or fine felt tipped pen will be appropriate.
