Opal Feine Merino 4-Ply Sock Yarn

The first edition of Opal Fine Merino was a resounding success! Made from 21.5 micron merino wool sourced from South America, giving it a soft, fluffy, and delicate texture. Like all Fine Merino Wool collections, it’s mulesing free. The chlorine-free EXP finish means the merino wool does not felt and can be machine-washed. Opal Fine (Feine) Merino Wool Edition 2 features three tone-on-tone colour ways and three vibrant options. It is ideal for lounge socks, cosy accessories, and snug, warm sweaters.
Stay comfortable and enjoy lasting wear with a combination of 75% superwash merino wool and 25% polyamide. The wool brings warmth, breathability, and moisture management, while the nylon adds durability and shape retention, even with daily use and repeated washing.
One 100g ball typically makes a pair of adult socks; larger sizes may need more. Use for socks, shawls, sweaters, gloves, or any project with dynamic colour flow.
The result is yarn that feels purposeful: technically reliable for everyday wear, visually striking in a way that reflects fine art rather than conventional variegation, and of course built to last.
