Knitting Jubilee

How do you make a large-scale yarn bomb or knitted art installation without having to do all the work yourself? By asking the public to help you out, of course. One weekend in June 2010, sculptor Dan Preston, jewellery designer Holly Packer, and some Superblue Design Ltd. employees took 7000 metres of rope, a giant circular knitting loom, and some large plastic balls to Jubilee Park at Canary Wharf, London, and enticed over 100 park visitors into knitting a 72 metre tube.

I'm wondering if I could try something similar the next time I'm behind schedule on knitting Christmas presents.
