New for Spring: Noro Tensan

New for Spring: Noro Tensan

Planning transitional-weather projects can be tricky: you want a yarn that’s warm yet breathable, lightweight yet stitches up quickly so you can actually wear your new pieces before it gets too hot out… does such a magical yarn even exist?

Thanks to the fibre and color geniuses at iconic Japanese yarnmaker Noro, now it does – meet new Noro Tensan!

Tensan, the Japanese word for “silkworm,” honors the ancient origins of silk — a fiber treasured for its strength, sheen, and timeless luxury. Blended with fine wool, this luminous yarn brings together warmth, resilience, and a soft, lightweight feel. Dyed in Noro’s unmistakable palette, where earthy tones merge with radiant bursts of color, Tensan’s flowing shades and rustic textures reflect company founder Eisaku Noro’s philosophy of drawing inspiration from the natural world:

“I was born and grew up in a place where more great unspoiled nature is left than anywhere else in Japan, so the world of nature is always close. Whether I am aware of it or not, I am inspired by it in many ways. By mixing colors, we can give a more natural feel reminiscent of oceans, mountains, flowers, trees and so on. From ancient times, Japanese people have accepted, enjoyed and been charmed by the non-uniformity, unevenness, and occasionally the coarseness of nature. It may be the base of us, and not only the basic philosophy for Noro yarns.”

With an appealing thick-and-thin single-ply construction, Tensan works up at a heavy worsted gauge into fabrics that are light yet warm, ideal for projects from textured cardigans and elegant wraps to statement accessories and summery tops.
