How to Flip a Polytunnel

Today I was very little use in a morning meeting about the future of sustainable food in the local area, having spent the past 3 days on the couch with a cold.  Luckily, I left the meeting with a mission in mind – to "flip" our polytunnel from last years crops ready for sowing this years crops.  A few hours later… voila!  Ready to go, and now we're almost ready to sow carrots, spring onions, kohl rabi and rainbow chard.
