This past weekend, spouseinbox and I worked on getting the pantry in better order.  It is a small closet with shelves on two sides and a door at a 45 degree angle to the back wall.  There was some wall space on either side of the door extending towards the shelves, so we installed pieces of 1×4 matching the height of the existing shelves and allowing a row of cans to be placed.  Spouseinbox further looked at the door and said that a shoe sorter would work perfectly there.  We spent a few bucks at the local big box retailer and now have a shoe sorter on the back of the door holding the small boxes of cake mix, tempura batter, etc.  That has freed up shelf space in the rest of the pantry and makes the items really easy for a visual check.
