You can see in the picture ( http://blog.evernote.com/wp-content/uploads/2012/08/moleskine_paper.png http://blog.evernote.com/wp-content/uploads/2012/08/moleskin... ) that the 'special' pattern is simply that all the lines are dotted (perhaps with ovals, or is that my imagination?). That's all that is needed, really, to find the skew of the paper.
