Initial study of woven tubing fence, in 4" diameter cast stone.
Spending some time a week later I re-drew it with a tighter weave.
(As of this post I have only been playing with it two weeks, self-taught. I think that with any in-depth amount of time drawing with Google Sketchup6 one will learn at an exponential rate. My biggest challenge at this point is in how long I can sit.)
