A few years back my house was renovated and I had a few unused clay sewer pipes left over from then. And since then I had been itching to convert them into planters. Finally got around to doing just that and am quite happy with the results! They are all the same length but I placed them at varying depths. They were a dull brown color so had to paint them with terracotta paint first after cleaning and scraping the surface a bit. Filled the bottoms with small thermocol pieces, put soil on top, put in the plants and voila!
