This is a very simple way to make a cool Hipster PDA using your basic Moleskine pocket-sized diary.

(For detailed information on what constitutes a Hipster PDA, see this article and this article.)

Step 1: What You Need

- Two loose-leaf binder rings, preferably small (I use 1/2-inch diameter rings)
- 3 by 5" Index cards
- A hole-puncher
- A Moleskine pocket size daily or weekly diary

Step 2: Open the Diary With Facing Pages

Turn to the inside front cover of the Moleskine diary.

Step 3: Line Up an Index Card With the Inside Front Cover

Taking one index card, line up the top of the card so that it's flush with the top of the Moleskine cover. I suggest centering the index card very slightly to the left of center on the Moleskine cover, as shown in the picture.

Step 4: Punch Holes

While holding the index card against the Moleskine cover, use the hole-puncher to punch two holes through both.

It doesn't really matter where you punch the holes, as long as they're fairly centered and well inside the boundaries of the cover/card. In my planner, the center of each hole falls roughly 5/16" inside from the top edge and approximately 1/2 inch from the left and right edges of the Moleskine cover.

Step 5: Create Any Other Index Cards for Your System

Using the first index card as your template, punch holes in any additional cards you want to add to the system.

Step 6: Collate Cards and Affix to Diary

Collate your index cards, and affix them to the front cover of the Moleskine by looping the loose-leaf rings through the holes, then locking them.

It's a good idea to loop one ring at a time.

Step 7: Voila!

Now you've got a planner!

Step 8: And If You Want...

You can flip your index cards around and secure them to the top of your planner, in case you want to remind yourself of something particularly important.
