So after gratuitous theme installations and customizations my tumblr site just isn't looking how I want it to. I've decided to just do the theme myself, but now I have one on there with all this extra stuff.
How can I go back to default layout so I have a clean slate to work on?

Go to http://www.tumblr.com/customize (you can get there by clicking the cog wheel in the backend and then Customize your blog). Click Themes in the upper left, then search and click on Optica, which is the default theme. Click on Use to take the theme.
