I make moving pictures!
From the business cards I've received from models and youtubers, my only advice is to keep it simple. Have your main contact information on it and don't use any images/logos that isn't your brand.
I think it's just a waste of material to make those cards. Too be honest I don't think people are actually going to watch your content, because you have a business card.
But if you're going to do it, make it awesome
I mean a "real" designer I can do better than Vista ;P
Heres a sample of some of my "business cards" i don't really use cards, they tend to get put in a pile a lot
