After much searching of blanket boxes, coffins, wicker beds, I have finally found an appropriate and well sized box for the new skeleton. And it gives him a window view.
I am very thankful to have found an antiques place on ebay selling off loads of old clock cases. Traditional grandfather clock cases are the wrong size and shape, so I am also grateful for the clean straight lines of art deco design.
But the main thing is that the skeleton is now protected from damage and dusting.
