I've made a set of 3 templates in 1280x720 for desktop wallpapers. They're simple and sparkly, kinda girly. But the next set won't be. This is just to get our feet wet.
So... here are the wallpapers.
Have fun and if you want specific types or sizes, email me at jljulian1 at gmail dot com. I'll start right after I finish my computer science homework.
