Yogurt containers are great for upcycling. They are perfect planters and can really be used for anything you want.
We used Krylon Fusion spray paint because it works on plastic. It did take about 4 coats to fully cover the label, but now you would never guess they started out as yogurt containers!
We were planting seeds that day which you can read about here, and Z used the new planters for his flower seeds and was very excited to see them sprout!
