I am so, so pleased with the result! I got the flooring sheet from my favourite ebay shop 'Little Green Workshop' for a bargain price of £6.99. (Their website is: http://www.littlegreenworkshop.co.uk/) It came with the promise of ease of use and I can totally pass the promise on- it really does.
I didn't need anyone's assistance in this which goes to show that anyone can use it! Hahah. It cut very easily and sanded well. You can see from the picture below that once you've started to cut the wood, it just breaks off very easily.
The backing is just thick paper and I think it might be sticky back stuff but it's not peeling off well so I'm going to attempt to glue it straight down.
So you've got an idea of size, I took this photo with a 1p piece on:
It would fit most standard rooms I think.
Finally, I'm not really sure what it is, but Little Green Workshop sent me a freebie, which is always lovely! I think it's meant to be a pot for a tree or something but I will put it in the shop once it's decorated :)
