Welcome to Isokumpu

Isokummun Kehräämö Oy is a company specialized in further processing of Finnish wool. Founded in 2018, the spinning mill operates near the Isokumpu sheep farm in North Ostrobothnia. The Isokumpu organic sheep farm is home to native breeds Finnsheep and Kainuu Greys, as well as their rare family lines, and the farm has been owned by the same family for five generations.

At the Isokumpu farm, the entire journey from wool to yarn takes place within a radius of four kilometres, as shearing, wool sorting, washing, drying, spinning and dyeing take place in the same area. In addition to this, the much talked about wool waste has been brought to a minimum.

The objective of the spinning mill was to produce unique yarn that you can't get anywhere else - succeeding in doing so. Our yarn is:

• 100% Finnish

• 100% wool
• 100% non-toxic

• 100% spinning oil-free
• produced without Eulan treatment (insect repellent), which is prohibited in many other countries

• colored with heavy metal free Greener Shades colors, which we sell exclusively in Finland

• smells like sheep and nature

• soft due to its lanolin content

• the hanks are knotless, and therefore the yarn is suitable for knitting machines as well

We use international standards for wool shearing and sorting, and laboratory testing certificates from the Wool Testing Authority Europe LTD for the classification of Finnish wool.


We were founding Suomen Keritsijät ry, whose goal is to create a new kind of wool culture in Finland, where international rules and orthodox shearing are introduced. In this way, we contribute to getting better-quality wool for sorting as well as washing and a high-quality end product to the market.

In 2017, Isokumpu was the first Finnish company to receive the right to use the LuontoHoiva quality label.
