SHE painted 700 plastic butterflies and he created a concrete man-horse.
Now the work of both sculptors will be displayed outdoors at Rookwood Cemetery.
Lee Bethel of Bundeena has been part of the art world for 20 years.
"The butterflies will go on a gnarled old tree, and they will twirl up the dead branches," Ms Bethel said. Pearl-topped pins will hold the butterflies in place.
Ms Bethel, who has a masters and honours degree in fine art and a degree in visual communications from the University of Sydney's Sydney College of the Arts, has exhibited at Hazelhurst Gallery, Gymea.
Adam Galea of Bexley is another of the 40 artists whose work will be part of the cemetery display. His concrete and steel warrior horse, resembling a mythical Greek centaur, is based on a World War I image.
"This was the last time horses were used in battle," Mr Galea said.
He works part-time as a mould-maker in a sculpture workshop and attended St George TAFE and the National Art School, Darlinghurst.
The artists' work will be part of the sixth annual Rookwood sculpture exhibition, HIDDEN, designed to demystify the site.
Rookwood open day is on September 14 includes talks, music, tours, food stalls and children's entertainment with a $10,000 award presented to an artist.
HIDDEN runs September 14 to October 12.
