What have I done?!

Have a look at the pic below, this is how I look almost every time when I decided to go with black eye shadow... I hope I'm not the only one haha

But I'm always sitting down to do my makeup, and then after I've applied my eve shadow the brush is covered in it and i usually need it for a lighter colour (use your brain, black first does not match up with light, I would look like a panda in that case with massive black rings around my eyes!)
And I can't see any paper close to me to wipe it of, and my leg is close... So if I'm not having a dress or similar, I'm doing this! Haha
