By the way - I know this is possibly too much to ask for considering you're giving your design away for free, but I noticed that the familiars are scaled to 3.5"x2" (aspect ratio 1.75) business cards, which are the standard in the US.
It's fine as long as I print them on my printer centered and all but I was about to order a batch from a professional printer and noticed that in most of the EU (+ UK) the default size seems to be 85mm x 55mm (aspect ratio 1.5454...).
So, the question is: Is there a possibility you could create a non-imperial version in 85mm x 55mm? :3
I could resize it through rasterization but that would stretch out the text OR I could recreate the little fellows in PowerPoint or something (retaining attribution of course!) but that would probably take longer for me than for you.
P.S. I realize I might be opening a can of worms here. There are many countries following a 90mm x 55mm or 90mm x 50mm standard. ;)
