Hi everyone. I am getting a calfskin Bible from the Trinitarian Bible Society and I want to make sure I take good care if it. I like to highlight, underline and write in my Bibles so I'm wondering what the best tools for the job are. I usually use a mechanical pencil and gel highlighter but not sure if those are the best. I use pencil cause I'm afraid of making mistakes. Also, I think I read somewhere once that pencil is actually bad for Bible paper. What do you suggest I use?
