I've been using junked drainage pipes as pot holders, the same way as you have done. It's a good thing to have certain pots above the ground. Here I keep a daylily pot for the present - see it on the far left of the picture. I'm so happy you are also doing such things. Another pot stand you can see here. See how our hanging pots are - it will have protusions - like a tail at the bottom. That is just perfect for the pipe holders!
