Some links have been included below that I find useful as an artist.
Artists and Illustrators
A monthly magazine for artists.
Purple and Grey

Derbyshire Open Arts
Every year artists in and close to Derbyshire open their studios during the May Bank Holiday to let members of the public see their paintings. This site catalogues the participants.
This one is where I list my smaller lower cost mounted but largely unframed art work for sale.
