If you don’t like your usual keyboard and want to decorate it somehow, or just the keyboard is a little bit worn, then this craft is for you. You’ll need washi tape, assorted colors that complement each other, scissors, scrap paper to make templates, a pen or pencil, rubbing alcohol, a paper towel or rag. Turn your laptop off and wipe down the keys with rubbing alcohol. Take a scrap piece of paper and place it over one of the keys. Press down on the key with your finger, and with the other hand, trace the outline of the key with a pen or pencil. This is your key template. Read the whole instruction in the source.
