Following the example of some book publishers, I’ve decided to start writing in my large Moleskine unlined notebook sideways on. The result is that I get a writing surface which is as wide as an A4 sheet and slightly shorter. As a writing surface it’s beautiful - which is more than can be said for my handwriting!
(I always have trouble with the size descriptions of Moleskine notebooks. They come in three sizes, Pocket, Large and Extra Large - which any normal person would call Small, Standard and Large respectively.)
