In reply to Gav M:
Go to the Offie. Purchase a 4 pack of Guinness or some suitable beverage that comes in nice tall cans.
Drink the said beverage.
Alternatively, do as I did and if you know where you can get some nice tall cans from, re-use them. This is what I did, becuase I don't like Guinness, but the cans are quite stylish.
When sober, use strong scissors to cut open the cans, and flatten them out.
cut two slits for about 1/2" along the ling ides, so as to create hinges. Using some suitabe cheap kebab/barbecue scewrs, create hinges so that the three cans can now nicely fit around your stove. If you keep the scewers nice and longish, you can anchor it into the ground.
Hey presto, one cheap, light, effective windbreak, and it costs very little.
Cheapskate, me.
