OK so for this build you will realy need very basic stuff.
What you'll need: a Big carboard box ( easily obtainable from your local grocries store.
A light fitting with wiring.
A roll ( or maybe 2 ) of heavy duty foil ( look for the HEAVY DUTY stuff ).
Some glue ( to glue foil to box ).
A few dowel sticks ( long enough to go right through box ).
A lekker BIG globe ( the higher the wattage the better ).
A peice of plank about the size of one of the small sides.

Method: Wipe the box clean with a damp cloth as to remove dust and stuff.

Cut the foil into pieces a little bigger than the panels of the box and glue these onto the insides of the box with the shiny side showing to the inside of the box, glue these onto all the parts showing to the inside even the flaps.

Now with the foil in place cut a slot of about 2cm X 15- 20 cm on each of the longer sides top and bottom( that will be on the side when you put the box on short side with flaps showing towards you ).

Now make some holes on either side from about a third from bottom and to the top for the dowels to go through.

Next make a little hole at the back bottom and put the wire trough there, connect the wire to the fitting.
Fit the fitting onto the piece of plank so as to prevent it from falling over.

Now all you need to do is to put your painted/ varnished item onto the dowels you put through the sides ( or you could hang it from 1 ).
And close the flaps switch on the light and leave it like this for a day or 2.

PS: Don't put the box somewhere where somebody will kick it. :silly:
