Thanks, but no. I'd seen that and tho' I think it's cool.... being a full on goth (even planting 'bat friendly' plants!) we're really looking for a standard, oblong mirror. We'll frame, and mount, it ourselves. We've a Salix Tumourso (Latin is not a strong point so forgive the incorrect spelling of the second word) and wanted to mount two mirrors to highligh it's 'winter plummage'.
I Think the Salix is known as 'The Devil's Claw' , me reckons it's growth will need to be curtailed somewhat!!
