I have been having a lot of fun with an app called LetterMpress, which is a virtual letterpress.
There aren't really any shortcuts; you have to arrange all the letters and secure them in place, just like the real thing. Then you pull the ink roller thing - okay, I haven't got all the terminology down yet - and, with a very satisfying sound, it prints your creation to an image file.
Here's my magnificent first creation. I'm not sure who I'd send it to.
