Lots of super suggestions, thank you so much!
Gracesgran there's an offset wide archway between the living room and the dining room extension. I hadn't considered looking at wallpaper for colour options, I'll certainly do that.
Lona, that does sound lovely, but does it show every mark? I always take my shoes off indoors but would have to train DH pdq
. I like the idea of silver grey I must admit, but how practical is it? The beige flecked carpet is ok-ish but 'traffic' ways show up despite annual cleaning and vacuuming daily.
That carpet's turned out to be a big mistake because it's had to be re stretched twice (it rucked up) and now the blasted thing is 'bubbling' despite being professionally cleaned. The shop went bankrupt so I don't have any redress although it's only. Few years old, and it wasn't cheap 
What's the best type of carpet to go for? Wool/wool mix or what?
Lovely ideas rubylady but I'm not that adventurous, sadly. I'm hoping to have a colour scheme I can easily adapt in the future.
to you wonderful GNs x
