This is like a hipster PDA, but better!. It is more durable, sturdy, and easier to replace cards.

NEEDED:
As many index cards as you want pages.
Two pieces cardboard, thin enough to cut easily (see step 2 for information on the sizes you are going to need to cut it to)
3 Binder Rings (available from Staples in a pack, may be called "Book Rings")

Step 1: Punch Holes in Index Cards

Choose how many index cards you want, and using either a one-hole puncher or an adjustable 3-hole punch with holes 2 and 3 removed (that's what I used) punch a little at a time to have the holes look like the picture.
The first time, punch the holes. The second time, use one card from the first time as a reference, so the holes will line up.

Step 2: Make the Cardboard

now, get a piece of cardboard and "punch" it (although a holepunch will probably not work and you'll end up using a knife :-P ) with the same holes as on the index card, except it needs to be slightly larger than the index cards and higher. Use the picture as a reference.

NOTE: If you want a "cover" cardboard, cut another piece exactly the same size as the Index Card. Then punch holes in it just like the index card and use that for the cover.

Step 3: Assemble

Put the binder rings in the backing cardboard first. Then add the cards. Then, if applicable, add the cover cardboard. Close the rings. You now have a stylish hipster pda-like organizer!
