I could not resist the temptation to make a lamp out of one of my empty cardboard rolls that I have saved when I bought poster. According to me you can not have too many light sources at home in the winter and the light I used was only two watt low energy lamp that gives a dull and cozy light.
.a cardboard roll
.low 2 watt bulb
Start to thread the lamp cord through the tube and when you are satisfied with how much you want it to show out of the tube fasten it with the tape. I let the lamp stay inside the tube because I used 2 watt low energy lamp which does not get hot, never use lamps that are stronger than two watt for this. But if you want to be sure about it all and just to be on the safe side, let the lamp stick out of the tube. And last I made a hole on the tube and hang it on to the wall. Done!
