I found blank card templates online and edited the sprites for the trainer, pokemon and badges in using MS Paint. (Works much better for this than Photoshop, actually)
There are a lot of templates available on various sites, but simply googling "trainer card templates" and looking at the images should get you some good ones.
I use
PE2K as a sprite resource.
EDIT- I edited together a spread of the 8 Unova badges, if anyone is interested. They should be lined up wight for the usual format.

Also, just got the second badge.

If anyone had trouble with Whitney in Johto, prepare to share a similar frustration. XD
