nice earth colour tones would be nice ,dulux are good paints wash and wear if you have children .for a feature wall ,paint your wall then grab a spongedab over the wall it gives a nice look to it . you can hire a floor sander , sand the floor back with a course gain and then clean the floor . u can buy a light colour stain paint it then sand and do it a couple of times . it will look fantastic when finished .
curtains try spotlight they have a great range . good luck
