Rich Jean+Ellie - the tarp is a great idea and this is my Plan B.
mjdb - thank you for the link, how did you find it? I have never heard of Studio, but they do sell a canopy windbreak for £20 - I have ordered it already.
HEJC72 - there is a Gelert canopy windbreak on ebay, I bid on it before mjbd response so am now hoping I do not win! There are several stripey green canopy windbreaks on ebay - but the reviews of them are awful.
I will post in a couple of weeks on my purchase. Thank you everyone.
I've got one of the ones from studio, although I got it last year it hasn't been used due to injury. There was a few of us on here that had the same idea at the same time after seeing a picture on here of someone using it!
I bought a summit one in a very pretty purple that doesn't match my bright green tent lol. Now though I don't even bother using the canopy, I bought a quechua tarp from decathlon plus some extra poles and it's a lot easier to cook under.
