Symmography

Symmography is the art of string using a piece of wood, nails, and string. 

The nails are placed in the pattern that is wanted and the string wrapped around the nails; I found it interesting as I started thinking as to whether this would work with crocheted or knitted lines, but on a larger scale.

The way this has shows the 3D I find fascinating, yet it looks quite simple as the string is just built up over each other to create the effect.
I'd like to try something like this, but with the knitted/crocheted string.
