I did not like my header anyways so happy to do this assignment. This is so easy;
Go to this website: http://www.wordle.net/create
Type in your website name and start playing. I’m not telling you how to do that because it is very intuitive. After I have something I like, I use the windows snipping tool to capture what I want, save it as PNG and I use that image for my header. As simple as that!
Let me know in the comments if you used it for your website, I like to see it.
