Plotulopi yarn plates in a pretty stack for a blog post about knitting with unspun yarn.

An Introduction to Plotulopi with Kelsey

By Maggie Nichols

Unspun wool? What are we even talking about? Don’t you need to spin wool to make yarn? Well, the answer is yes, but also NOPE! Yarn is generally fiber that has been spun to add strength. But, due to the dual-coated nature of Icelandic wool, you can actually knit with the unspun fiber without needing that added strength to have a stable fabric. It’s called Plotulopi!

Plotulopi consists of the unspun tog (long, outer fibers) and thel (shorter, inner coat fibers). The tog fibers give the yarn structure and stability without needing spinning. The thel adds softness and loftiness to the yarn, but wouldn’t hold together as well without the tog. If you’ve knit with Lettlopi before, Plotulopi is one of the two plies in Lettlopi. It’s exactly the same fiber, but half the weight and unspun. 

You can knit Plotulopi single for an approximately sport-weight yarn, but can also knit it double to approximately Lettlopi (worsted/aran) weight, and even three or four strands together to get a bulkier yarn. You can also knit it at a wide range of gauges. As I mentioned, it’s listed as a sport weight, but it can be knit even more tightly for a dense fabric, or even more loosely for an airier fabric. Being unspun, Plotulopi is very lofty and fills up the breathing room you give it. 

It works well in colorwork, because the unspun fibers lock together when knit together and then blocked. Finally, because it’s unspun, some people say it feels softer than spun Lettlopi because all of the fibers are pointed in the same direction along the “grain” of the fibers, instead of sticking out of the spun plies. 

Plotulopi’s uniqueness also leads to some quirks. Because it’s unspun, it does pull apart in a way that spun yarn generally does not. It comes in plates instead of balls or skeins because of this, and you need to unwind the fibers for a length before knitting instead of pulling as you go. The upside is if you need to reattach a break, the fix is an easy spit-splice away.

  • I was a lucky gal. Gifted bag of this yarn. Two white two natural, and three dark. I have never worked with it and didn’t know what to do. Thanks for your information in the above article, as i now have some ideas. Any suggestions are always appreciated. Thanks

  • Thank you for this article. I am very curious about Plotulopi and wanted some more information about knitting with it before I bought the yarn. I have knitted with Lettlopi and now I am ready to try Plotulopi. Sounds very nice!

  • Thank you for this – I LOVE Plotulopi and my reintroduction to it was through your Altheda kit (Jen Steingass had the most divine patterns for lopi!). I love that less than 3 ‘plates’ will make a sweater – basically 8oz of wool, and it’s so light! After knitting with plotulopi, I find lettlopi to be rather heavy.
    I do use something like Einband with the cast on and the cast off to give it a bit more strength, but only for one – two rows, works wonders! I hope you continue to carry this magical wool! Cheers!
