As a moving person,   I try to reduce both   movable   and  the permanent items .  When I was struggling to hang my expensive clothes(?) I got this idea

* You may see simillar ideas in youtube videos  , It seems great men think alike or Fools thinks alike .

I am aware that Patenting the  ideas is  the only way of protecting   the ownership  of your design. However  it costs a lot so   we dont care who has

invented  it first  :)
