The easiest way to tackle this project is to measure all of the shelves at once. Since it's going to be covered, the front of each shelf is a great place to record the measurements and while you're at it, number each shelf so you can match the numbers up later on.
Copy the measurements and move to your saw. If your shelves wrap around like mine you'll want to cut one end with a miter for a finished appearance. For straight shelves, use straight cuts. Don't forget to number the back of each piece as you cut them, and don't forget your safety glasses.
Once you' ve made all of your cuts, bring the pieces inside and match the pieces to their shelves.
Use a nail gun or some four dee finish nails spaced every twleve to sixteen inches to hold the sleves firmly in place. Make sure you have a nail at each end of the piece to hold it secure.
Once the pieces are in place fill the nail holes with some spackle and then paint the shelves and fronts for a seamless look. I'm Mrs. Fixit and it's just that simple!
