After looking through different organizers, I realized that if I didn't want to spend a ton of money, I would need to figure it out myself. I needed small containers that would fit a brick of clay, and containers that could seal well so the clay doesn't dry out.
Solution! I used Ziplock 4oz square containers, printed labels with my Brother label maker, and stuck them all in a covered tub from Target. I used 24 containers for the different colors I had.
I turned them upside down to make it easier to see the color. Of course, I had help!
Total cost? Just under $12!
