Is there a good FAQ somewhere on DIY concrete pots? Sorry for posting two separate topics, but this really isn't related to my inquiry on terra cotta pots.
DIY concrete pots?
I'm not sure if this is what you're after, but there's a thread on this forum from tomtom about making papercrete containers. I saw some activity on it recently so it shouldn't have slipped too far down the page yet. There's also a Hypertufa & Concrete forum where I bet you'll find a ton of info.
