Step 1: Assemble Your Stuff
You need what's in the picture.
Step 2: Cut the Front Loose
Step 3: Cut the Pad Off
If you have any buckram or the like, now is the time to glue a little strip of it, carefully measured for width, over the rough-cut areas of the cover. I didn't bother; I'm a little short of buckram this afternoon.
Step 4: Add Page Points
Step 5: Add PostIt Strips
Step 6: (Optional) Separate the Signatures
Step 7: Put It Together
Step 8: Use
That's it. If you've been using a Hipster PDA this is the way to carry it around, and the pocket makes it that much more useful. New cards go in the back and you write on the cover, with the elastic holding the card, or you write straight on a blank card at the front of the stack: the pocket lets you take down five or six cards of new material without messing with the binder clip. The cover can be flipped back and information on the front card can be viewed easel-style.
As a glance at the sidebar will show, this is released under Creative Commons. If you like it, and want to show gratitude...you could send me a Moleskine! I go through a lot of those things. There's room for improvement here, in particular the pen could be held somewhat more securely...give it a try and let me know what you think.
