I'm sure it has been discussed here before, but internet forums are so transient it can't hurt to discuss the topic again. How do you mark up your bible? What type of writing devices do you use? Do you have special symbols or colors that denote certain topics? Do you underline,highlight,write notes? I am a crayon and fountain pen welding fool for mark ups. My crayon is a standard yellow Crayola. My pen is a Lamy 2000 extra fine nib with Diamine Monocco Red ink. I have a pigma micron in black for underlining, but I don't underline much, crayons are just so much more fun. Extra important (to me) verses get the crayon treatment. Cross references and notes get an --> * at the beginning of the passage and a verse number keyed note in the margin.
