Ok, I posted a sneak peek in the last week, but since then I've done a little more work. I'm still tweaking the layout, so forgive me if the values on the card are wrong. I've found a place that will print decks of playing cards in different sizes. The first one below is a standard poker sized playing card. The larger ones beneath are 3.5" x 5.75". They're much larger, but still perfectly practical for my purposes. I'm thinking about using the larger cards for the core units and then maybe using poker sized cards for equipment details.
I decided to split units that have multiple equipment options into multiple cards. I think this will make things easier as you'll only have what you need on a given card with nothing extraneous.
I've been made aware that the background is way too busy. I'm still debating on how best to handle that. I want some sort of imagery. I might go with a Magic the Gathering style border or something. I'm just not sure yet.
