due to the dread Caliche soil here in Austin: it shifts everything so what you put down does not stay there. A good fabric base will just slide about on the ground (and hopefully the sides will stay up).
I am sorry I was not more clear about stating my needs.
I need to make one and set it up, then find out just how practical it is. Thanks for the help, I will try the spiral-on-a-cone one (sounds like something you get at Dairy Queen.)

Thanks. I really did not phrase it right - I am trying to make a good herb spiral.

Everyone is hepped up on making them out of rocks, but frankly they don't look like spirals. I want a nice snailly spiral! The one Elisei did comes closest, and I'm going to try and do it.
Unfortunatly, I have NO idea how to plug in a plug in so K-tools is just beyond me at the moment. The other planter drawing is nice but way beyond what I am trying to make-just a wound up fabric triangle sewn spiral. I'm gonna fill it with dirt and herbs.
Thanks.

It seems absurd, as this is not a complicated shape, but I have had a rough time making it. I want a Fibonnacci spiral about two feet high in the middle and lowering as it gets bigger: that is a right triangle with the 90% corner on the ground in the center, then the smallest angle at the outermost point of the Fibonacci spiral. I thought all I had to do was make the spiral and then lift the middle, but NOOOOO. I suppose I could make a small 'handle' and pull up the center point but so far I have had no luck. I will have another spiral (flat) on the ground (the whole thing is a design for a planter, and is to be made of fabric.)
Can anyone help me here? I'd be very grateful.
