Where It Comes From

The Merino sheep is a breed of domestic sheep that produces the merino wool. They originated in Spain, and for hundreds of years there was an export ban on them so other countries couldn’t profit from breeding them.(1)

In the 18th century, flocks were sent to the courts of many European countries including France, Hungary, The Netherlands, Prussia, and Sweden. Many breeds have developed from the original.

These animals are bred and raised in many places in the world, like Australia, New Zealand, the United States, and countries in South America.

How It’s Made Into Yarn

Spinning takes the raw material and turns it into yarn. First, wash the wool to clean it and remove impurities. Then, the fibers are combed or carded to align them. The fibers are spun by hand or machine. The spinning method affects the thickness consistency.

Types Of Merino Wool Yarn Breeds

  • Australian Merino – this is the one with the softest fleece, and the standard other merino breeds are compared with. They don’t have horns. Rams of other breeds have long horns close to their heads, while ewes are hornless
  • Booroola Merino – They’re like most other merinos, except they’re more likely to give birth to multiple lambs at once
  • Delaine Merino – They’re mostly found in North America, prized for their long life and hardiness
  • Gentile di Puglia – This is a breed native to Italy, often known as the Italian merino
  • Merinolandschaf – They’re bred for meat and wool
  • Peppin – A ram of this species produces up to 40 pounds (18kgs) of wool a year!
  • Ramoubouillet – These are a French breed

How To Wash Merino Wool Yarn

Here are the care instructions for merino fibers.

  • Wash in cool water with a mild soap. (Only machine wash wools marked “superwash” on the label.)
  • Gently squeeze out water and roll in a towel to remove excess moisture. Lay flat to dry.
  • Don’t iron or bleach.

Always check the yarn label for instructions specific to the yarn you’re using.

Does It Shrink When Washed?

If you’re worried about merino wool shrinking, don’t be. This fiber is less likely to shrink than other wool because of how it’s processed. The fibers are tightly twisted, so they don’t loosen up as much when wet.

How To Soften Merino Wool Yarn

Here is a quick and easy method to soften merino wool yarns. Washing it after you’ve finished knitting always helps! Don’t use fabric softeners, they reduce the merino wool’s ability to keep you warm or cool.

What Do You Use It For?

Wondering whether you should use it to make a project? Here’s why this fiber is used to make yarn. I adore knitting with Merino wool. It feels lovely during the project and it is even better to wear!

I’ve made shawls and socks with this fiber and it makes my creative heart skip with joy! The range of colors are amazing. It’s often used for projects and things like shawls, scarves, sweaters, hats, mittens, socks, baby items (it’s gentle on the skin), blankets, and throws. It’s also used to make arm knit yarn.

Here’s a video about a fair isle sweater designer who uses wool to make her beautiful designs.

This knitting technique is beautiful!

Common Blends Using This Fiber

Here is a list of common blends using this yarn, and why they’re created.

  • Silk/Merino – The silk adds strength and durability to the merino’s softness. This is a high-end yarn because of the two luxury fibers
  • Alpaca/Merino – Alpaca wool is often blended with merino to add warmth and softness to the finished product
  • Nylon/Merino – Nylon is added to socks and other items that need to be durable. The merino wool helps with moisture control and keeps the item from smelling
  • Bamboo/Polyamide/Merino – A blend used for socks

Cotton fiber (fibre) and merino is another option, but it’s rare.

Where To Find It

Here’s where to find this yarn: at a yarn store, at big box stores like Michaels, Walmart and Joann, or in online brand shops. Here are brands or manufacturers of Merino wool yarns to try: Ella Rae, Debbie Bliss, Rowan, and Koigu.

What’s The Price Like?

This fiber is on the higher end because of how it’s processed and the demand. Blends are cheaper than 100% merino wool yarn. Light fingering weight, fine, and chunky weight yarn is more expensive than Aran, sport, or worsted weight.

It’s a luxury yarn, but much cheaper than things like bison yarns. For info about expensive fibers, read my blog post.
