Flower pots with built in drip trays are my favorite way to test out working with larger amounts of clay on items that are just a bit technical lately. As a huge bonus, they're super useful and fun! With the built in tray, there's no need to try and find a saucer or plate that matches the pot and your plants never drown in a puddle of water. 
 
The space flower pot was glazed with a red horizon fading into the ether in mind. Or maybe you just like the colors. I certainly do!
