Have you seen the pantry thread on the Gallery side? Perhaps the pantries there will give you some ideas.

Here's our pantry. It's about 3 ft wide x 5 ft deep. The back wall is sloped because it's under the stairwell. It originally came with 2 ft deep shelves along the back, and things were always getting lost there. DH cut back the shelves to 1 ft deep, and added the racks on the sides to make use of the wall space. They work better here than larger shelves for what I needed to store. The brooms, etc are stored on a rack on the wall behind the door.

You really need to think of what you want to store in there and how best you can fit it in. We didn't have an electrical outlet in ours, but if so, I might have put our toaster in there or had the charger for the hand vacuum or some other electrical gadget find a home there.

Allison showed her amazing pantry and compiled a huge lot of other helpful photos.
