Sometimes, pieces of firewood look really good. You may just place it somewhere as a very simple decorative elements with this certain touch of nature. Now, why not placing a hidden (or at least semi-hidden) LED-stripe inside, which illuminates the room with warm, indirect light?

So, that I did. The other firewood piece with the heart, formed a white threat and a couple of nails was just another idea of what you can do with firewood.
