For what it's worth, I bought the mentalism piece Behaviour Pattern's, from Alan Chitty, about a year ago. I liked the effect and method, but not so much the supplied props.
I decided to make one up for myself and used a moleskine for that. Took me about two days of love and labour. I rather like the result, it looks like a curious personal set of sketches, doodles and numbers normally found in the scattered remains of a paranoid schizofrenic,conspiracy theorist or other colorful eccentric. ;-) And that fits the effect rather well.
After that, I got the idea to turn a moleskine into some sort of mysterious container (like the old bibles, seen in films, that carry a miniature revolver or flask, hidden in some cut out pages).
I can picture to make the moleskine look like some arcane diary, with cut out pieces for (for instance) miniature gypsy curse cards, three silver coins or a haunted key. Could be an interesting way to introduce your little close-up/bizarre magic.
