I stuck my moleskine in my new K2 cover to see if it would fit (lower profile and all). It won't. I just bought all the supplies today to start making my own books, since I can't find something I likeakjak said:You know what I'd really like... An Oberon cover for the Moleskine notebooks. I love those so much and they're a really nice size to carry around. The 5x7 journal is a little too big.
Even better if they'd do a cover for Moleskine "reporter" style.
