Some people were overly grandiose. A friend of mine, living in an ex-council house, had a huge chandelier suspended from the ceiling in her miniscule lounge. Window blinds became narrower and were highly popular in black or red. Standing up-lighters - particularly with black supports - became a wow, and wall up-lighters swept back late in the decade, in antique or modern stylings. Once again, the watch word was style, darling!
In the 1980s, we stripped out the darned awful wallpaper which had blighted the '70s (those designs dated back to the late 1960s anyway) and went for pastel colours or strange slanting striped wallpaper which made your eyes go funny. My mother bought some particularly awesome wallpaper for the lounge circa 1984: it showed part of the interior of what appeared to be some sort of castle, with an archway, some stairs and a window repeating all over it. It was grey and white. LOVELY!
