Mate, I built my own dew sheile that cost me $10 for materials. I reckon its more attractive than the genuine article!
Its just two pieces of attractive pattern black ripple cardboard. Ripple on one side, smooth on the other. You can decide which way you face the ripple to look how you want. Its just wood glued along the seams, and some black hundred-mile-an-hour tape to hold it all together and dress it off.
Finishing touches were logo's downloaded and printed from the net, glued on and a final coat of spray on lacquer from the shed.
Whaddya reckon?
