Texting yourself on an iPhone?

I'm trying to start a Zayn Malik and Justin Bieber imagine account on tumblr which will include fake texts, blurbs, and drabbles. I want to know how I can text myself on my iPhone so I can make the fake texts. Btw my account on tumblr is: ballerinamalik

Just save your number as Zayn Malik on your contacts and message yourself on Messages. That should do it.
