IN THE STUDIO
Through texture, color, shape, and eco-friendly materials, Sienna’s soft sculptures explore nature's adaptability, take a stance against the unsustainable and unethical practices of the textile industry, and embody her dedication to challenging the prevailing currents of consumerism and the excesses of late capitalism. Through gentle art activism, her artworks help raise awareness and inspire action on important environmental causes and encourage audiences to reflect on their roles in social change.
As a fiber artist who traverses the expectations of what can be done within the realm of textile sculpture, Sienna’s art is a vivid testament to her signature approach, where the tactile interplay of texture, a wild and diverse color palette, and shapes inspired by the geometry of biology are harmoniously woven with her dedication to environmental integrity - gently reminding us of the beauty of our planet and our shared responsibility to preserve it.
INSPIRATION & VISION
Every year, billions of animals suffer and die in the textile industry - including for wool, mohair, cashmere, leather, fur, and feathers. At every stage of production, these animal-derived materials are hazardous to our land, air, and water, and in many cases, to the workers who make them. That’s why, as an eco-conscious and vegan fiber artist, Sienna uses plant fibers, recycled, and upcycled materials to ensure her art has a minimal impact on our magnificent planet.
Sienna’s textile sculptures are built upon time-intensive, repetitive processes using the development of traditional textile techniques in contemporary methods. She combines spatial utility, modern aesthetics, and a deep-rooted ecological conscience to craft artworks that transcend form and function. Her fascination with irregular movement, lack of consistent edges, and repetitive shapes have informed her work and have captivated the world.
