In previous years, HWAT invited a guest artist to exhibit in the taster exhibition. Guest artists exhibited their work at the Harleston Gallery during the annual Art Trail.
Previous invited artists have included: the potter Clive Davies, abstract artist Jazz Green, environmental artist Jayne Ivimey, and the sculptor Derek Nice. HWAT now has Associate Artists, who are all invited to exhibit with the group but do not participate in the annual Art Trail. Associate Artists: Jane German, Dee Nickerson, David Page and David Rock.
