Long Electricity Cable Storage

I was tired of untangling 35 meters of electricity cord every time I wanted to use it , and when I only needed 10 meters long cable in the first place!

Made from cardboard box, and packing tape as required. A serrated knife or box cutter is the only tool you need.

Cut slits as shown in diagram and push inward the edges.  I left about 2 meters of cable loose (male end), which reaches the wall plug, then wrapped the remaining cable round and round the box.  Finally I cut a slot which stows the female end till use. 

  Very easy now to transport, plug in, unwrap as much as needed, and re-wrap neatly when finished!
