Last January we had a blog posting asking for some crochet help on this piece of art. I know for myself that I was afraid that the time table was a little too aggressive for my abilities. I don't know if anyone was able to participate.
The latest issue of Vogue Knitting arrived in my mailbox yesterday, and in it was an article on the Amsterdam installation last winter. There are a couple of links that you will find interesting. The first, http://www.choishine.com/TheLace.html, shows the installation over the canals in Amsterdam, including a video. The second, http://www.choishine.com/TheLaceMaking.html, shows the construction and the install, again with a video.
