I like dark or jewel colours, velvet curtains, stained glass, Tiffany lamps taxidermy and skulls, Persian rugs on parquet floors, beamed ceilings, and things like planetary globes and orreries.
Most of my furniture is inherited or scavenged.
I started out having a red library room, with floor to ceiling bookshelves, reclaimed parquet, ancient bashed red leather chesterfield sofas and an oak pedestal desk reclaimed from a skip, but the book collection has outgrown the room, so now there are bookshelves around the house. My vast SF and occult collections are going nowhere, even if they were available on kindle.
Old filing cabinets, sprayed red, contain my SF and pagan magazines collections, and we have a large coffee table made out of sleepers, at just the right height for the dogs' tails to sweep everything off.
On the spare bits of wall in the house, I have some nice pictures, picked up in auction or by artist friends, some taxidermy and some drums.
In my mainly green parlour, I have another reclaimed parquet floor and a tile and slate fireplace, vintage almost but not quite William Morris velvet three piece suite, picked up at auction, and some proper antiques: a long case clock and a davenport desk.
My kitchen is bright yellow and green, with wooden units and brightly coloured tiles in that random chequerboard pattern that is now really outdated, but I like it still.
I have committed these and a lot more sins… 😀
