Step 2: The Cutting
The first step is to cut all those sheets of paper in half. After your done take the uniform sheets and split them into piles of 4.
You could get away with more but I find 4 works the best.
Next you should take those sheets and fold them in half.
Since I wanted to copy the Moleskine design I took a leaf out of an old notebook and cut the paper down to that size.
What made the process easier and more uniform was after, I made the first set of 4 leaves, I used it as a guide to cut the rest.
paper clips work Great for this.
PS: Take your time. Don't force the scissors or it will end up looking bleh.
