Right before leaving for Poland, I found this great site that used a Magic the Gathering card design program to make some warlord power cards. I took this idea and made some of my own that can be printed out double sided. This worked great and I started to make them for the psychic powers available to Eldar. Than I went on vacation. Fast forward to getting back I go to finish the cards and for the life of me I can't figure out what settings I used to extract the cards. I still made it work but the process took a lot longer than needed. Lesson learned, pay attention to what you are doing and take notes!
Anyways here are some of the card images and a link to pdfs for both sets of powers. One note when printing out the backs may appear slightly off center, this seems to be a function of how the printers flip the paper/grab the paper. I found it easier to let it be slightly off and adjust my cutting to make sure the backs are consistent.
