I prefer to write poetry longhand, usually, at least for the first draft. It’s not romanticism; it’s forcing myself to slow down a bit. I’m pretty particular about the pen and the kind of notebook, too. I like Moleskines, of course, who doesn’t? But my favorite is a faux-leather-bound big journal that I got when I taught a writing camp for high school kids. That was years ago, and it’s getting pretty full of notes at this point, but it’s hard to find something nicer.
I remember reading someone who suggested that poets should use cheap spiral bound notebooks. Great, if you can. I used to. But the pages get hard to turn, the paper feels like crap, and the spirals catch on everything in my shoulder bag. So I’m willing to splurge.
I used to keep a notebook for ideas, but I found it fell apart in my pocket and men’s clothing doesn’t always have a convenient place to store it. So now I use my “memory palace” to keep track of ideas. It works better and doesn’t lock me into a particular phrasing too soon.
