We've been there before with that suggestion, see Gurn Post here but yesterday a local resident tweeted a slightly different take on it. It's worked elsewhere and perhaps there is a funding framework there that could be copied here.
"Eight community groups were given the opportunity to explore different areas of their town, to find out why they are such special places, using nature as a canvas to create their own artworks."
We've certainly (and thankfully) got enough nature around us here to do that, anyway here's the suggestion with a link to further information.
@GurnNurn how wonderful would it be to have this in our empty shops in #Nairn? A great idea for NICE perhaps?http://t.co/2O5pPSfeLK
