Umpire Line-up Card

[bake17]

Hi all..I am a brand new "rookie" volleyball official doing high school matches. I have had a lot of help in my clinics and scrimmages, but one thing that I would like some input on is how do ya'll keep your line-up cards? I am using an index card now and I have seen a dozen examples of how to lay the card out for subs, time-outs etc. Wanted to see if there is some simple easy way you veterans do it that I might be able to use. Some of the ones given me are real elaborate.

Thanks,
