I reorganized my spice cabinet! I just squeal with excitement when I open the cabinet and see the matching jars lined up. I put my most frequently used spices in larger jars (chili powder, curry powder, 21 Seasoning Salute, oregano, thyme, bay leaves, and cumin) in the front. Then I put all my sweet spices to the left and a few of those are big too (cinnamon sticks, pumpkin pie spice, allspice, mulling spices).
In general, I buy spices whole and grind them as needed. But I go through pumpkin pie spice, chili powder, and 21 seasoning salute fast enough that I just buy those already ground.
I also took the bottles I don’t use very often (like pickling spice and dill) and put those in a plastic tub on the top shelf – it’s still easy to grab if I need it, but it doesn’t obscure my view of the regular use jars.
Other than keeping the sweet spices together (which I use for chai) , I also like to keep hot spices together (chili powder, cayenne, ancho, chili pepper flakes, etc.) and herbs together (rosemary, marjoram, basil, cilantro, chives, and parsley).

Yay!
