Most people use a computer for work or play. When you're on the computer often, the keys can get worn out. Once the keys are worn out, the lettering can begin to fade. After awhile, the lettering will be gone altogether. Unless you know the keyboard keys by heart, figuring out which keys you're pressing is a little (and frustrating) guessing game. Instead of playing that game, make a quick set of alphabet and character stickers to place right onto the old keys.
Making the Stickers
So you know their exact sizes, measure every alphabet and numeric key as well as function, shift, enter and tab keys. Open a Microsoft Word document on your computer and type each character of the keyboard, spacing the letters, numbers and characters quite a bit. Purchase large stickers in the size of a sheet of paper (8 inches by 11 inches) from an office supply store. When printing a lot of smaller stickers, it's best to use one big sticker and then to cut each sticker down to the correct size. Once your characters are in the Word document, print them on a regular sheet of paper to ensure they are far enough away from each other to cut around them in the proper measurement. If the characters, numbers and letters are all correctly spaced, print them on the large sticker sheet.
Once the large sticker sheet has been printed, you can begin to get the characters ready for the keyboard. Use measuring tape and the measurements of each character already taken to draw a square (or rectangle) around each character. Keep the sticker backing on while you cut around each character on the square or rectangle that is drawn. Once each character is cut out, place it over its own character on the keyboard to ensure the sizing is perfect. Remove the backing from one of the characters and carefully place it over its faded key. Continue doing this to all of the characters until the entire keyboard is finished with its new key stickers.
