You need a sticker (like this one) and you need thick, white piece of card stock. I used the back sheet of another sticker.
Trace a circle the size of the sticker circle and cut!
Remove the sticker from its backing and place the white circle onto the sticky part of the sticker. Apply the entire piece to your Macbook and you now have a cooler Macbook than you did before!
