 Although he has also occasionally used gouache, and more recently has often worked in acrylics, Edwards' original medium of choice is oil paint.This is used on any smooth board, ideally hardboard, which is primed with "gesso".Following from preliminary sketches, images are constructed on the support with a hard pencil before being developed using washes of a neutral coloured acryclic, usually brown, a technique Edwards says he borrowed from 'the old masters'.
