That's the one SaraSeahorse I have mentioned it before on here in another thread, they are based in Cheetham Hill, Manchester and you can go down if you contact them beforehand, the only problem with ours was some of the stitching about 2/3rds of the way through the roll was a bit rough on some of the seams but I just cut it out.
It was great in the bedrooms as most of it was covered but the living area needs some sort of fixing down as it is light material but made a fantastic difference to the tent, but it did only take a couple of minutes to shake of any bits and straighten up, we were thinking maybe of some velcro pads on each corner just to keep it tidy but not tried it yet.
On eBay they only had listed a 10mtr roll but when we went down we got a 20mtr roll for £2 a mtr, we had a bit over so that is going in the front porch when we get the Sun Canopy sorted out.
I was tempted to get a fitted carpet for our Norfolk Lake but its extra weight to carry and I was worried that it would get damp and smell.
I have to admit it would be nice to have carpet underfoot at night though.
Whatever option you choose you won't regret it, we wouldn't go away without it now, ours is quite bulky as its for the whole tent but it is easy to push the individual pieces into nooks and crannies (except for living area!) and it's not that heavy, the good thing also is because it's fleece it's easy to clean and dries quickly and it doesn't run.
Tigang. We have just ordered the Norfolk Lake and had a Sun valley 8 carpet for our Indy. Turns out that the measurements for the Norfolk will mean that our current carpet will fit... can get them on Ebay a bit cheaper than the specific norfolk lake ones!
