While we were at the fabric store buying the headboard fabric, I picked up some little fake pearls that would act as the "spice" in the jars. Next was to figure out what jars to use, which is when the green idea hit me. Whenever I use the last of a specific spice in my spice cupboard I put it to the side of the cupboard to remind myself to buy another bottle of it. I took these empty spice jars, filled them with some fake pearls and then used my hot glue gun to glue them shut.
We now have fake Cloves, Garlic Powder, Cinnamon, Oregano, and Cinnamon Sticks in our play kitchen. And I have enough pearls left over for a few more bottles once we use up the existing real spice.
