Australia’s Belinda Broughton (polymerbelinda) could have stopped right here. She applied pan pastels to a sheet of polymer. Then she scratched through the top layer of jagged triangles (technically sgraffito) to make an even more dynamic design.
Pop that baby in the oven and hang it on the wall!
I saw a painting but Belinda had earrings in mind. Either way, it was fun to watch and may make you reconsider pastel possibilities.
