[6] She bought a small hill farm in Dyfed, breeding Welsh cobs[1] and specialized in painting traditional equestrian portraits until starting to sculpt in the 80s.

Heather spent many years perfecting the translation of her complex work into bronze, pioneering a technique that made them indistinguishable from the driftwood original.

[8] Her life-size driftwood horses became her hallmark and in 1999 were featured in the Shape of the Century 100 Years of Sculpture in Britain at Salisbury Cathedral.

She exhibited internationally on a number of occasions, including, in 2007, as artist in residence at Arte Sella in Borgo Valsugana, Italy.
