I had it like this for a long time because I could not think of what else to do with it. Obviously it had to have floors and wallpaper, but I couldn't decide what would fit. Finally some time ago my son's girlfriend, who had been bitten by the dollhouse bug, sent me a parcel of small things she had found at flea markets, including a container of tiny mosaic tiles. Just what I needed after long days of work.
I think the result is stunning. It reminds me of Gaudi. Perhaps it was the intention. I still need to decide what to do with the walls.
