Make Your Own: Yosemite Mail Icon
For a while now, I've wanted to make a PSD for anyone to be able to make their own Mail.app icon. Get an image that means something to you, whether it be royalty, a symbol for your country, a cartoon character, or a famous person!
All you have to do is paste in an image, rotate it 9°, and size it accordingly. Change the name of the location too, inside a Smart Object.
