File this one under Things I Should Have Thought of Sooner: I wrote up a quick tutorial for changing your theme for Tumblr Themes.
Also: re-worded the top bar a little, and made some visual changes to the tags at the bottom, and some other smaller tweaks here and there. And, yeah, a few ads. You understand. (If you don’t: I’m a greedy British man. Get off my lawn.)
And added some more themes, naturally. Inky’s Obsidian is particularly worth having a look at.

This theme isn't yet complete, because I'm lazy. Don't mind the rough edges, and the unexpected appearance of this message at the bottom of the page.
