With the help of Art Apps like Procreate, Art Rage or Sketches you can easily add embellishments like digital scrapbook paper (and lots of color) to your Bible Art Journaling page on the iPad. I am using the Bible Art Bible, which is a navigable pdf-file and can be downloaded from my website, and the Goodnotes-App to start and then the Sketches App.
