5: Here a small drafting triangle is lightly tucked up against the
letterboard of this freight car so that a colored pencil can be
streaked downward along the side of the car.

follow the edge of the triangle without digging into it, as
shown in Photo 4.
Photo 5 shows another easy trick you can do with just a
single triangle. An interesting weathering effect can be done
using colored pencils to lighten or darken individual boards
on double-sheathed boxcars and refrigerator cars, to rep-
licate water streaks. To produce this effect, I lightly tuck a
small 4” triangle up against the letterboard, then stroke the
colored pencil downward along the edge of the triangle.
This keeps the streaks parallel with the boards. Photo 6
shows the resulting effect.
More techniques can be accomplished using two triangles.
One is the ability to make parallel or perpendicular lines.
