The basic principle is simple. Cut your fabric to the required size, attach it to something solid which is then braced to hold it in place, add reinforcement and pour the concrete into the flexible form.
Many shapes and uses can be created with this method, but we will focus on a simple column. You can use this system for standalone columns or posts, or for posts that attach to an existing wall. We will describe a standalone post, as this is a little more difficult.

Step 1: Base
- Dig a hole, about 12 inches in diameter, where you wish your post to stand, whether it be at the base of an existing wall or on its own. The depth of the hole will depend on what type of force will be exerted on the post.
- Place metal reinforcement in the hole, raised up on rocks or plastic (you want concrete under any metal, so that there is no chance it can leach water and rust).
- Level the metal (both east to west and north to south) and hold it in place with a couple of boards between it and the ground. [If the post is against a wall, attach the metal to the wall if possible, with a gap in between them.]
- Pour concrete into the hole to just above ground level. Make sure you tamp it down every once in a while to ensure that the concrete completely fills the hole. We use a 3:1 cement to sand/gravel mix.
