Chris, Yours picture of your succulent display above is Beautiful!
You must have weed blocker fabric in there, I don't see a single blade of grass or weed in that bed!.
I like the little hypertufa pots too. Do you make your own? Are they freeform or do you use a mold? I haven't made any small ones, but I have made several large ones using plastic lined cardboard boxes as a mold. I know some people also turn a bowl upside down and pack the material over the bowl to make the round ones.
It sounds like you are an accomplished craft person, with all your beautiful wreathforms too.
I do other concrete crafts, mostly leaf casting with real leaves. I do like that media since it is so durable and long lasting. I have several of those stepping stone molds too.
