There’s a couple different ways to make the plarn but this is super simple, all you need is scissors, and you can do it as you go. That said, I would follow a single-crochet tutorial online with some kind of string even like a shoelace or something first because I found the plarn somewhat difficult to work with at first and it would’ve been much harder if I didn’t already have that basic stitch down.
I mentioned this on another sub but they were super displeased that I interrupted their extremely important political discourse about politicians and political parties memeing at each other. I suspect they may have also been upset that I was referencing activities they have difficulty engaging in; upcycling being only one example.
