The full writeup is also available at my blog, kitchen table scraps along with lots of other foodie nonsense including how to store spices to maintain their quality.
Step 1: Decide where to locate your spice rack.
First, pick a location for your spices. Mine works great on large, exposed side of my fridge, but that may not work for your kitchen. If you buy a cheap metal shelf support, your spices could be organized in a line almost anywhere in your kitchen. You absolutely need to think about accessibility and appearance when deciding where to put your spices, but also think about heat. Opaque tins will keep your spices safe from light damage, but exposure to heat can be equally damaging. So avoid placing your spices near your oven or on a wall that gets hours of direct sunlight.
