Since the Jesus latte I realized that I don't have to white out the entire top of the cup in order to draw portraits; I just have to have a big white portion in the center of the cup. That way, I can also use the crema from the outer ring to draw with, instead of using leftover crema from a shot glass.
And yes, I do look at a photo for reference while etching. I'm not artistic enough to come up with originals of famous people.
Oh, and sorry about the glare in the photo.
