Last time I ran a Fate-based game was Spirit of the Century and I had the players fill out 3" x 5" index cards by hand. This was great as I had everyone's skills and aspects in front of me and could sort them by initiative order. Unfortunately, they were inconsistent and hard to read.
This time around, I decided to print out standard cards that the players could fill in. Initially, I stuck with the 3" x 5" index cards, but found that they were a little cramped. I then moved up to 4" x 6" index cards. These proved to be more complete, easier to fill out, and, incidentally, easier to read.
I also ended up making a card for tracking multiple unnamed NPCs.
Both cards are available for use:
If you end up using them, please leave me a comment as to how well they work for you.
