I want to make the concrete/cloth planters

Already tried it and it didn't work. The concrete dried and when I turned it over it just fell. It seemed there wasn't enough concrete on the cloth or something ...

My first question would be how was your slurry mix ( the consistency) ? I generally try to make it like lumpy gravy I guess I would say. You don't want it too watery or too thick either. You will see the lumps( for lack of a better way to describe them) when you lift your cloth out of the slurry pan. Second, how long did you let it set up??? 24 hours should be enough unless it's been really rainy or extremely humid. They dry pretty quickly if they are in the sun. Also cover with a plastic bag or drop cloth after you let them set up a bit in the sun. With all that being said I have had some that just flopped also. Can't tell you why this happens. It just does sometimes. The one right next to it from the same batch of slurry could be fine and the next one just doesn't harden. My advice to you is just don't get discouraged. Keep trying. You can do it. Btw. I do not use hypertufa. I use only Portland cement sand and I use a concrete bonding agent( found in the masonry isle at your big box home improvement stores) and water.

Would the fabric choice make a difference? I can see where if it didn't hold enough of the slurry, it might not work. I love the look of them though. I know I have seen them made with old towels.
