The Initiative Cards in this download include eight 2 1/2″ x 3 1/2″ cards on one 8 1/2″ x 11″ sheet. They include examples of how they can be filed out for both PCs and Monsters. What I do is have each player roll for their PC’s initiative and write the results on their card. I do the same for the monsters. I then gather all the cards and sort them in initiative order before the start of combat. I can then refer to the stats on the cards during combat.
For those of you who (like me) prefer a larger card, here are the same cards only these cards are 3″ x 5″: INIT_MONSTER_CARD_3x5
