needs to be pen, graphite from your pencil doesn't keep for long, I draw using graphite and if it gets pressed by the book or pad it smears around and off the page. This is from the longevity view if its not going to be kept for long or very important then whatever you want. You could seal every page as you write it using spray sealer like I use on my artwork.Thanks everyone for the responses so far. One kinda silly question: Pen or Pencil in your journal? I see some have mentioned using a fountain pen....which I personally don't think is for me. I keep meaning to bring a pen upstairs to use, but so far have been using the pencil that was on my bedside table for some reason....
I'm also considering changing WHEN I write in it. It's been an evening before bed thing, but sometimes it gets late and I'm forcing myself to do it. The plus side is, I'm keeping the journal by the bed. If I do something different timing wise, I may need to find it a new home. Oh well, I'll figure it out.
