Castaways is a Danish design project founded by textile artist Henriette Giese, that specializes in creating unique, sustainable clothing using the nuno-felting technique.
Castaways uses this technique to transform discarded materials – primarily recycled silk saris from India and second-hand clothing – into new, high-quality garments.
- Technique: Wool fibers are felted directly into existing fabrics like silk, cotton, or linen.
- Result: This is used to creates a new living textile with structure and depth.
- Aesthetic: Because the materials are recycled, every piece of clothing – whether it is a blouse, dress or scarf – is a unique creation, with its own expression and story.

Henriette Giese has authored a book titled Old Clothes in Disguise, which serves as a guide for using nuno-felting to repurpose old clothing into new designs.
