About Heidi Hennessy Cashmere

Heidi Hennessy’s knitwear is crafted from the finest Grade A cashmere, spun in a centuries-old Scottish mill renowned for its heritage and commitment to quality. Using a distinctive double-stranded knitting technique, each piece is both luxuriously soft and exceptionally durable—resistant to pilling and fully machine washable. These timeless accessories are thoughtfully designed to elevate everyday wear without compromising on comfort or elegance.

Every item is personally designed by Heidi and produced in small batches using a combination of modern and vintage knitting machines, as well as hand-finishing techniques. With a strong focus on zero-waste production, Heidi partners exclusively with mills that uphold the highest standards in sustainable water practices and responsible cashmere processing—ensuring each piece reflects a deeper commitment to craftsmanship and care for the environment.
