I would like to start a discussion on markings and symbols used in
woodworking. I am refering to things like the cabinet maker's
triangle, methods of what component is what and what side of a cabinet
is what. I find myself changing my method of marking often because I
am not convinced that the one I used last is the best.

Some of the replies to this type of discussion are "use whatever works
for you". But that creates problems when you might come up with a
symbol that can be misinterpreted. Or, like the Roman numbering
system, not the best concept to use.
