Your index card might look like this. R ead each card, and see what categories it fits. Perhaps the first card contains something about the Heroine. Use your index card to see which hole that is. Now, next to Heroine, you have a sort of u-shaped channel where there used to be a hole.
P unch out several other categories, as appropriate.
I f you need to, add some more categories to your index card, as many as you need. Hang in there a minute. D o the same for all your cards. Some cards should receive multiple punches. Perhaps you have a card that mentions your hero s reaction the first time he sees your heroine.
