I recently picked up a pamphlet about the Highland open studios while buying some supplies at my local art shop. The open studios is a directory for finding and comissioning artists based in the highlands. There is a website at http://www.highlandsopenstudios.co.uk/. It also details when and where all the artists are exhibiting, including art trails to follow.
Here are some of my favourites from the website :
Sun on the Firth 1 by Claire Bois - http://www.clareblois.co.uk/index.asp
Dusky Squall over Raasay by Fiona Matheson - http://www.fionamatheson.com/index.asp
