During her life as a painter Prunella constantly made graphic images in etching, screen-printing or lithography. She first came to The Curwen Studio in 1959 to work at the suggestion of Timothy Simon and these images originated on the use of transfer paper – a method she continued to use for the rest of her life.

She studied at Chelsea School of Art and taught at Wimbledon College of Art until her death in 1999. She achieved eminence as a painter late on in life, winning the Jerwood Prize earlier the same year.

Prunella was always held in high esteem by her fellow artists.
