This coaster is from a painting inspired by Pennines in Calderdale, West Yorkshire. We don’t get sunsets on the valley floor, where I live, you have to go high up to see them. This coaster is matte ceramic and cork backed. The matte gives a velvety depth of colour. It is 9cm square and washable, however it is not dishwasher friendly because of the cork back. Each coaster is sold separately.
