"Plötulopi is unspun Icelandic wool (pencil roving) and is traditionally used to make authentic Icelandic Lopi sweaters.
Plötulopi is often knitted using two or three strands, resulting in garments that are exceptionally light and airy. Plötulopi is surprisingly strong once knitted thanks to the unique characteristics of Icelandic wool.
Gently wind the required number of strands of Plötulopi together or knit straight from the plates.
A single strand of Plötulopi is very delicate. It can be strengthened by twisting it lightly or by knitting it with one strand of Einband [or other lace weight yarn]. Plötulopi is great for felting, hand spinning and many other things (Istex)."
