So I have a Blackbook and it's very nice, but every time I shut the lid, after a while I begin to see a faint dirty outline of the keyboard.
Now I know there are various places >>online<< where I can buy a cover that I can place between the screen and the keyboard to prevent it from happening, but I am wondering if there are perhaps any substitute materials people here use other than online purchases or know a retail store that sells something that can do the job.
Thanks!
