This exquisite piece by illustrator Sonia Poli is called Vegetal Gradiant. It’s made from paper and mounted in an embroidery frame. Sonia writes:
While following my path through the paper collage world and I simply came up with this. Tired of frames, I wanted my collage to act more like a sculpture. After playing around with fish for my previous exhibition, I used the same technique (gradient from navy blue to a lighter/brighter color) for another favorite thing of mine, leaves.
