Drawing on the vast knowledge of this group ( I only have half vast knowledge)-- Whatz the best way to put lines on a road or marking on a marshalling yard- I've not had good results with a white pen.. maybe using the wrong scribbling device.
Thanks
Fred
Just like the real thing, spray paint and stencils.
In the Z world, air brush and masking tape. Arrows,
etc can be printed on label materials, cut them out
with razor knife, then use them as "real" stencils.
