Here's a few of my creations. I started with hypertufa many years ago but I really love working with cloth and cement. I have been working on a 5 foot tall version on the castle to plant succulents in. I will post pictures of the process when I finish in a week or two.

Cloth "towel" planters (cut from a $1WalMart bath towel, draped over a paint can)
