Gelert Peg-less Travel Washing Line.
Gelert's Travel Washing Line is very cleverly designed because you don't need pegs to attach clothing. This peg-less laundry line comprises of two lengths of shock cord twisted together, so you can just put your clothing in-between the two of them without the need for pegs.
It comes with clips and suction cups for attaching it between two points but can just as easily be tied. It's made of elastic so it has a variable length up to a maximum of 2.5m.
