What is Lopi wool?
Lopi wool (pronounced "lopay") is a unique type of wool from Icelandic sheep. It is particularly famous for being the traditional material used to knit the Lopapeysa, the famous Icelandic sweater with a distinctive circular pattern around the collar and shoulders.
What makes Lopi wool so special is its unique composition. The fleece of the Icelandic sheep is composed of two distinct types of fibers:
– The "tog" (or outer fibers): These are long, strong, and water-repellent fibers. They provide excellent protection against the elements.
– The "þel" (or inner fibers): These are shorter, softer, and insulating fibers that act like down.
The unique feature of Lopi wool is that these two types of fibers are blended and carded together (often as an unspun or lightly spun roving) rather than being separated. This combination gives Lopi wool exceptional properties. It is incredibly warm while being light and breathable, thanks to the airy structure created by the blend of fibers. The water-repellent outer fibers give it a certain water resistance, making it ideal for outerwear. It's a robust wool that can last for generations.
Although Lopi wool may have a rustic appearance and initially feel a little rough for some people, it tends to soften with washing and use.
The presence of plant matter, such as hay or grass, in lopi wool is completely normal. This is a sign that this Icelandic wool is natural and minimally processed, in order to preserve its unique qualities. These small pieces are usually easy to remove by hand while working the yarn and are not considered a defect, but rather a testament to the authentic and rustic character of this atypical wool.</sp
Our Lopi family consists of three thicknesses:
– Barber: This is the traditional Lopi wool, the thickest of the spun wools (bulky/chunky type), ideal for very warm and insulating outerwear such as coats, thick sweaters, or throws. It is very robust and offers excellent protection against the cold.
– Piteraq: This is one of the most popular and versatile Lopi wools. It is lightly spun, which makes it more durable. Of medium weight (worsted/aran type), it is suitable for both indoor and outdoor clothing. This is often the go-to yarn for a first Lopapeysa.
– Knik: This is the finest of the Lopi yarns spun. It's a very lightweight single-ply yarn (lace/light fingering type). Ideal for delicate projects, shawls, lace, or to be combined with other yarns to add lightness or a touch of color without too much bulk.
In summary, Lopi wool is a unique wool, emblematic of Iceland, appreciated for its thermal qualities, its resistance and its versatility, particularly suited to warm and durable sweaters.
Lopapeysa
Knitting the Authentic Lopapeysa
The Lopapeysa is the traditional Icelandic sweater, recognizable by its distinctive circular yoke adorned with colorful patterns. Appearing in its current form in the mid-20th century, the Lopapeysa has become a powerful symbol of Icelandic national identity and self-sufficiency following the country's independence. It represents not only a treasured craftsmanship but also a deep cultural connection, often knitted as a loving gift within Icelandic families. The word "Lopapeysa" is a combination of the words "lopi," meaning the woolen yarn used for the sweater, and "peysa," meaning sweater in Icelandic. This term literally means "woolen sweater," and it can only be called a Lopapeysa if it is made from Icelandic wool.
This garment is unique due to several key elements:
– Material: It is hand-knitted with lopi, an unspun wool from Icelandic sheep.
– Construction: It is usually knitted seamlessly in the round, from the bottom up. The yoke is created using a jacquard technique (multi-color knitting).
– Design: The yoke patterns are often geometric or inspired by Nordic nature, traditionally using the natural colors of wool (white, black, gray, brown).
When you first wear an Icelandic Lopapeysa, you may notice its rustic texture. However, after the first wash, the garment will become noticeably softer and more pleasant to the touch. Additionally, over time, the wool will gradually soften, so it is advisable to give it some time to adapt. For sensitive skin, it is often recommended to wear it over a thin garment.
Maintenance of the Lopi
To properly care for your Lopi wool and preserve its unique qualities, here are the essential points to remember:
Frequent airing: the ideal reflex! Let it air out rather than washing it every time; Icelandic wool is naturally odor-resistant. This is an excellent practice, highly recommended, as it preserves the fibers, maintains the shape and suppleness of the piece, and reduces the risk of felting. To air your Lopi effectively, choose a well-ventilated location but not one directly exposed to intense sunlight or pouring rain. Avoid direct heat sources, and do not place it near a radiator or fireplace to air it, as excessive heat could damage it. Fresh, dry air works wonders for refreshing wool. A night outside (if it is not raining and there is not too much humidity) can be very effective.
Forget the washing machines! Whether it's for washing, spinning, drying, or ironing, pamper your handmade work with great delicacy!
Wash only when necessary (in case of visible stains, after prolonged use, or if odors persist).
Use constant water temperature (20-30°C or cold) for washing and rinsing, as well as a gentle natural detergent (pH neutral), ideally with lanolin. Please note: to preserve natural dyes, the use of soap or detergent with an excessively high pH, vinegar, baking soda, etc. (particularly to soften the fiber) is to be avoided, as this will permanently affect the color.
No agitation or twisting, handle your garment gently, squeeze it gently to clean it, and knead without rubbing or twisting to prevent felting. Rinse several times following the same principle (some wool detergents, such as Eucalan, do not require rinsing!). Gentle spin by hand, squeezing gently without twisting, or roll in a towel to absorb excess water. Flat drying is essential on a clean towel, restoring its shape, in the open air and away from direct sunlight or heat sources. Never hang a wet Lopi garment, as this will distort its shape. Pilling is normal at first and can be easily removed by gently removing the pills.
By prioritizing ventilation and following his advice, you will take care of your Lopi wool creations which will remain beautiful and comfortable for many years.
We recommend using Eucalan detergent available in our shop, haberdashery section.

The « bloom »
What is "bloom"?
The term "bloom" is very relevant when talking about Lopi wool.
It refers to the way a yarn's fibers "swell" or "open out" after washing and blocking a knitted piece. The fibers relax, unfurl, and fill the small spaces between the stitches, creating a more uniform, fluffier, and often softer fabric. This can make the yarn appear thicker or the fabric denser than it was on the needle.
Icelandic wool is particularly renowned for its significant bloom after washing. This phenomenon is related to the unique fiber structure: loosely twisted carded wool containing two types of fibers: tog (long, strong outer fibers) and þel (short, soft inner fibers). When the knit is washed, the þel (down) relaxes and expands, filling the spaces and creating this blooming effect.
Warmth and Lightness: Bloom is essential for the insulating properties of lopi sweaters. The expanding fibers trap air, making the garment incredibly warm despite its apparent lightness.
Texture and Softness: Before washing, Lopi can feel a little rustic, even rough for some sensitive skin. The bloom softens the fabric considerably, making it more comfortable to wear. This is why it's crucial to always wash and block your swatch and finished Lopi project to fully appreciate the result.
Knit and Jacquard Uniformity: The bloom helps hide small irregularities in the knits and bind the colors together in the jacquard. Patterns blend better, and the fabric appears more consistent and professional.
Tips for optimizing the Lopi's bloom:
Gentle washing: Hand wash your project in warm water (not hot to avoid unwanted felting), with a mild wool soap (neutral pH). Avoid wringing or rubbing.
Soaking: Let your item soak for at least 20-30 minutes to allow the fibers to relax and absorb the water.
Lay Flat and Block: Gently squeeze out excess water (without wringing) and lay your item flat to dry, ideally blocking it to the desired size. The flat drying process allows the fibers to settle into their new, "opened" position.
