In her post of April the 8th Fiona (a Passion for Minatures) wrote about the wall plugs that appear to come with the coppertape system for creating electric light in a doll's house. I wrote a comment on this post about my coppertape system and how I agreed the rather ugly wall plugs had to be hidden behind tiny objects.
However the drawback of the coppertape system is you need to make plugs in the walls. The electricity plugs are far too big and obvious. I try to hide them with some furniture or tiny accessories.
The same trick I applied to the kitchen ceiling: the wires of the kitchen lamp end beneath the bath tub. If you look well, you can still see the grooves I made initially for the wiresystem; in the back wall of my house are still tiny holes where I wanted to pull the wires through. I can still do it if I choose to....
Then there was the problem of the hearths. I decided to hide the plugs behind them as you can see in the pictures below.
