You tend not to look very much at the ones on the stairs, unless it is at the end of a corridor, or at the end of the stair well. So, I have my favourite painting on the end of the stair well, so that we see it every time we go down the stairs. On the walls, which I dont really look at a lot, I have an engraving that dx didnt like, and some prints that he bought that I dont really like. Also, in a dark spot, I have a few watercolours, so that they wont spoil in the sunlight.
Im an ex artist, so I take all this stuff very seriously
