Just wondering, how in the woild do people make the red borders? I wanna know
You mean the different colored cards? Look for a tut if you want to make it yourself. If not, go to a shop. May I suggest the shop in my sig?
You can recolor the card. Many tuts in tutorial section.
Most use Photoshop, and some use GIMP, however, I did see one for MSPaint a while back, on a very high page number now probably...
