The middle one was my first, and not decorated by me; those are Elrond's twin sons, Elladan and Elrohir, up at the top, by the bye. It has some of my planned novel Sunshine and Gossamer but is mostly full of Wordcrafter - lots of messy scribblings on Wordcrafter.
The one on the far left was my second, this time decorated by me. The sketches of the two women are of Lizzy and Jane Bennet, drawn by professional artist Niroot. The drawing in the bottom right of the anthropomorphic cat sitting at a burning typewriter is from the webcomic Lackadaisy. The middle image is a drawing of Legolas with "If You Can Read This, The Dwarf Fell Off" written on the back of his tunic. Over on the right and at the top are some signature graphics (original art not mine); the one on the left says "blue jeans in Tera" (Wordcrafter), the silhouetted man says "Justin King" (Wordcrafter), and the woman up top says "Marta Rais" (White Sail's).
And the one on the right is my current notebook. Like my second, it has an Arabian horse on the left (for Marah from Wordcrafter). It also has a couple signatures - one for Justin (again), one for Ethan, and one on the right that says "I answered you in the secret place of thunder." It also has an adorable picture by a gal who...seems to have deactivated her deviantART account. Then I've got a cover for Sunshine and Gossamer and another for Tempus Regina, my other planned novel.
I write the scene on the right-hand page only; it's easier that way. At the top I mark the story and sometimes the chapter, if I'm actually advanced enough to have a chapter list.
I also write notes on the top of the page, usually having something to do with the teaching. (The top note, for those of you who are peering curiously at it, is the quote from Wives and Daughters, "I'm not saying she was very foolish. I'm saying one of us was very foolish, and it wasn't me.") On the left-hand page I write the location of the scene, more for the fun of using elaborate fonts than for anything else, although with White Sail's it is helpful. For instance, the scene I was writing in the right picture took place in Boston; others take place on the schooner Enterprize, and I'll note that and the location of the ship at the time (if in port). I also use this space for writing more notes, or for scrawling furiously when I can't think of anything to write.
And sometimes I write on the bulletins our church has for Sunday mornings. This is for Tempus Regina, but I'm not going to translate it for you.
*The cat featured in some of the above photos is Buster. He was more interested in lounging than in posing, however, so he looks a bit...well...loungy.
