Sorry its taken so long to reply! Things got sort of hetic, but I should have time to work on the background for you by the end of the week.
Anyway, would you like the background to fit the screen, or fit a few entries instead? I could make a page in a journal, or I could do a full spread thats more like John Winchesters journal, it depends on the kind of layout you'd prefer and how much space you want to fill on the computers screen.
