I like to record my ideas in notebooks. I like the medium-sized Moleskine-type notebooks, because they're big enough to be useful, but small enough to be carried around most places. I prefer the Leuchtturm brand to the Moleskine brand, because the ribbons are nicer, the pages are a tad wider, and they come with labels for when you're done using them. The Moleskine ones do come in much more exciting colors though.

My four notebooks thus far. The Leuchtturm notebooks come with extra spine labels, so all my notebooks can have them when they're closed out.

Notebooks A and B are Moleskine medium-size. Notebooks C and D are Leuchtturm medium-size, which is bigger. Notebook D has orange fabric because it's the Whitelines digital paper. Fancy!

Notebook A, with a sketch of a tooling plate. Notebook A was a Moleskine with blank pages.

Notebook B was a Moleskine with a grid. The grid is way too strong though, and makes it hard to find what you're drawing. I also used a Table of Contents in this book, which worked very well.

Notebook C was a Leuchtturm. The Leuchtturm books all have pre-printed page numbers, and are slightly bigger than the Moleskines. This one has a dot grid, which almost disappears if you're not looking for it.

Another shot of Notebook C. The dots are easier to pick up in this one.

Notebook D is a Leuchtturm with the Whitelines Link paper, also with a dot grid. The paper is colored a faint gray with white dots, and it's got pre-printed page numbers. In the corners, there are datum targets for use with the Whitelines Link app.

This is the same page from Notebook D, as captured by the Whitelines Link app. It will take the picture automatically once it sees all four datum targets, and then it's supposed to remove the background and deskew the image. Results may vary.
