Dumb idea #342
Take a foldup gazebo like this
http://www.supercheapauto.com.au/onl...126512#details (just got a catalogue, they are on special for $139)
Leave the roof off and remove the roof supports. Leaving the legs joined at the top by the side supports.
Wrap the whole lot in tarps or other material of your choice.
Drill new holes in the legs to set the height you want.
