I don't know that I can say I never look anything up: I do ensure that I have things correctly written. Being a multi-language programmer, I don't trust my memory for a lot of boilerplate.
But, if you'll settle for "wrote by hand in a text editor and didn't copy/paste from a tutorial," my entire website is an example of that. Here's index.html.
I'm not insane, of course. I'm going to copy/paste boilerplate from my own websites, to cut down on stupid errors. In this case, that'd be <head>. However, that was written by hand originally, so it's still all originating from my own fingers.
