I found this tree art image on Pinterest the other day: http://pinterest.com/pin/146085581632358190/
I absolutely love this idea. You attach markers to tree branches and place a canvas underneath the tree. The wind moves the branches and creates the marks on the canvas. How cool is that?! :)
I will have to remember this and try it in the spring!
The artist is Tim Knowles. You can see his website here: http://www.timknowles.co.uk/Home/tabid/262/Default.aspx
He does other art with balloons, full moons, windwalks, and nightwalks.
The one thing that is annoying about Pinterest is if you find something on the website and then go back later it is almost impossible to find the image again. I spent about five minutes searching for the tree art image. However, I did find some interesting tree art ideas.
(Really great blog! Definetely check it out!)
You can purchase these tree rings for $150 here on Etsy:
