The Brits are miles ahead of us in North America, when it comes to the use of willows for sculpture (though Patrick Doherty and Alastair Heseltine are two notable exceptions).
Here is my latest discovery, from a post that is no long available on The Guardian's website:
"A herd of life-size wicker elephants arrives in Hyde Park today for a two-week stay. The 13 elephants are specially commissioned by charity elephant family, which is working with the Royal Parks Foundation and The World Land Trust to raise awareness about habitat protection projects in the UK and India. Here we chart the elephants' journey from the workshop to the banks of the Serpentine."
There are 9 more photos on The Guardian's website, including some of how the elephants were constructed. There are a few more interesting details on the BBC website.
On our website, I have more links to artists who are creating willow scuptures.
