Diploma of Fine Art year two students worked on a collaborative experimental drawing with their teacher Di Holdsworth.

Together they have recreated an image by American realist painter Edward Hopper out of toast.

More than 90 loaves of bread, which equates to about 2000 slices have been toasted to four different shades in order to represent the different tones in the four by four meter image.

Students came across a problem when they realised their household toasters weren't up to the job.

They had to enlist the help of Peter Simpson, the operations manager of tourism and hospitality at the Nepean campus to bake the bread in its commercial kitchen. Di Holdsworth said the drawing class has been more like a hospitality lesson.

"Students have been baking, toasting and passing around recipe cards about how to cook the toast and how to make the special PVA glue," she said.

"It's quite funny to watch."

Every year drawing students from Kingswood TAFE challenge themselves with the difficult task of experimenting with a portrait, by using non-traditional art equipment.

"We run this project so students learn the fundamental and traditional elements of drawing, which in this case include colour and tone," she said.
