I have a deep, narrow and dark pantry, and three roommates so no one ever knows what's already been bought. Some organization would be great - once we ended up with four open bags of sugar and no flour. I might honestly label different shelves with things like "dry goods" and "cans" but we will need to move the order around - one of my roommates is scared of heights and can't use a step stool. :)
DIY Home Design - think of use of space / function as though certain space is more expensive real estate (easy access space) vs. cheap real estate space (hard to get to, requires a step stool, too deep so you can't see, etc.) In your organizing think of items that should be within easy access and they get expensive real estate . . . it helps to sort and group items.
