I carry them in my purse for shopping lists. I tuck them around the house, for easy access when a great thought bursts onto the scene. And, of course, I keep 'em at the ready near my computer. (I should also say they always - ALWAYS - end up with at least a few pages of preschooler doodles.)
Here's my current collection:

Some you see are filled with miscellaneous scribbles and jots. The two upper-right ones are the journals I fill with tidbits about my daughters' childhoods. The floral in the middle, top row, is the one someone personalized as a gift for me. And then the celery green and mauve-y books, together in the middle, along with the light blue (sandwiched in the corner between the two beefier blues), came as a packaged set from a hobby store. They're thin and smooth, with beautifully blank pages.
I am going somewhere with this.
The sandwiched blue one is the new home to some very crucial notes for my WIP. After yesterday's post about whether or not I should outline, I decided I'd make an effort. Especially after Jenna suggested maybe I was turned off by the word "outline," and the connotation it came to have through years of school papers and reports, not the actual output of one. Call it a blueprint! she said.
And so I am. The little notebook is perfect. Thus far I'm designating one page for each chapter, for key points. (Those will be written along with the book, as I see where each chapter will take me. So it's kind of outlining, kind of not.) The margins are already being stuffed with things I'll need to keep in mind down the line. And I started writing a character sketch for the main character, as well.
It pleases me. And not just because I'm using an adorable notebook.
Do you have a (healthy) fetish?
