The colours she uses in her art are predominantly green and blue, symbolising the new life brought forth by water/rain. Hermien regularly uses vertical lines in backgrounds to depict rain. She often cuts vertical lines on her lino blocks or uses gravity to drip diluted oil paint – the liquid finding its way downward, much like rain.
Hermien enjoys using mono printing as art making medium. These mono prints are made using actual plants and a homemade jelly slab. She uses printers’ ink and a roller to print the plants directly onto paper, and her body as printing press.

Lino printing is another medium she loves. While cutting into the lino with her carving tools, Hermien finds similarities between fynbos and human beings. As humans, we too, must sometimes undergo a process of cutting away to ultimately show our true beauty. Fynbos, likewise, gets scorched by field fires, to produce new life and a better flowering season.

Hermien also works in oil paint and mixed media collages. She uses embroidery stitches like French knots and cross stitches to hold the pieces of the collage together.
