The beginning of the book has an excellent description of different journal book types (with advantages and considerations of each kind) and a thorough discussion of mark making tools and paints; Gwen's favorite journaling paint is watercolor and mark making tool is the micron pen! My favorite tools are spiral bound Aquabee Super Deluxe 93lb paper drawing books (will take dry and wet media well), woodless dark/soft graphite pencil, Pitt black markers, Derwent ColorSoft pencils or Koh-I-Noor woodless colored pencils, and Penguin pan watercolors. Sometimes when I am travelling and don't want to take both the colored pencils and pan watercolors, I substitute water soluable Derwent colored pencils.
With so many pictures of journal pages from different artists, it was easy for me to get inspired to write, no matter what I think my handwriting looks like! As a bonus, I later found in Gwen's book a handwritten font I've fallen in love with!
