I'm kidding. I have plenty of my own. Well, at least I had plenty. That was before I got on this kick of using plarn. In case you hadn't heard, plarn is "plastic yarn," more specifically, yarn made from plain old plastic grocery bag type of bags.
I tried the plarn ideas around the internet, but they all turn out a fine plarn that's more suitable for table cloths or baby bibs, maybe. I tried knitting with it, but it's not very yielding and my old hands began to hurt after a little while.
It took awhile, but I figured out what to do. If you make the plastic bag strips much wider - about four to five inches instead of one - the plarn will be fatter. Okay, so that didn't take a lot of brains to figure out, but if you've tried using the one or two inch strips like the youtube videos show and found them hard to work with, try again with much wider strips.
It will take more bags, but isn't that the idea, anyway?
Don't stop with plastic grocery bags, though. Plastic bread bags, produce bags and any other clean plastic bag will do. Thinner plastic just needs wider strips.
Why not use plarn to knit or crochet? It's free.
