If you’re the type that gets a kick out of upcycling, then you should really add this nifty little trick to your repertoire. I use this plastic thread to sew buttons and the like onto my plarn creations. I find it a lot easier than just using plarn (plastic yarn made from cutting plastic bags into strips) and a lot more satisfying than using cotton thread/yarn.
Update 07/2015: Most plastic bags in the UK are now biodegradable, which means that they will fall apart after a couple of months. When you make any plarn projects, please make sure that you are using bags that aren’t biodegradable. You will be very sad if your slippers/rugs/bags crumble and fall apart!
Plastic thread made from Plarn is remarkably strong and feels a bit like thick dental floss when you work with it.
It is so easy to make too! Just take a piece of plarn and pull it slowly. You will notice that the plastic becomes see-through. Occasionally you will have a solid bit right in the middle, but that will disappear as you pull. It reminds me of a spark running along a gunpowder line – sort of like in the cartoons.
If the plastic snaps, that’s ok too, because you rarely need more than 15 cm’s for sewing on a button and you’re bound to get at least that. If your plastic keeps snapping, you’ve used a dodgy bag or you are pulling too hard. Try another bit/bag.
I have found that Asda bags here in the UK give me the best results and I can usually get a good 3 meters of thread before it snaps.
Please bear in mind that not all bags are created equal, so you might need to search around a bit to find your perfect type of plastic bag. It will usually be the one that stretches when you try to break your plarn at the end of a project.
Earmark this post, because you will need this info for my upcoming pattern for Plarn Crochet Slippers.
