Yesterday, I printed off a version of the Vacchetta Tarot deck on 110lb. white card stock. I also printed a design I found on the reverse sides. You can find the Vacchetta deck here:
Now I just have to raid my wifes art supplies to get some coloring pencils! Here is what I have done so far:

I'm planning on picking a few primary colors for each of the suits and then go into more details for the major arcania.
I trimmed the cards tight to the lines but now I'm thinking I should have left a border. Not only would this look better but it would also allow me to round the corners with a corner punch. I might have to re-think what I've done so far or maybe just treat my current deck as a prototype.
