I am now making plarn (plastic yarn) from plastic bags I’d saved up for the purpose. I have heard of two methods. This is the one I used, which I found was prevalent in YouTube tutorials.
First, I laid a plastic bag out on my craft table. Then I used my hands to smooth it out from bottom to top. The static cling it created helped keep the bag flat.
Then I folded it in half and repeated the smoothing process.
I folded it in half and smoothed it again. As you can see, the bag now formed an even strip. It was now ready to begin cutting.
I trimmed the bottom seam and the top with handles. These trimmings go into a recycle bag.
Then I began cutting the body of the bag into strips about an inch wide. (I am making this plarn for crouching a basket so I wanted it to be a little thicker.) Each smaller cut strip unfolds to be a loop of plastic.
For stringing it together to make the actual plarn, I took an open loop and hold it behind the previous loop.
I ran the rest of the open loop through itself around the previous loop. I made sure that the two sides of the previous loop would be evenly split and gently pulled the knot snug. I had to be careful because if I pulled too hard, I could break the loop.
I continued joining loops until I had a good number and then wound it into a ball. I leave an end out on the last loop so I can continue to add to it easily.
I now have three plarn balls (one for each color of bags: white, yellow, and brown). The tutorial I watched on making plarn suggested 20 bags as enough for a “basic project.” My white ball has around that many so I may go ahead and begin making a basket.
I hope this is of use to others interested in using those bags they keep forgetting to recycle. Check out YouTube for more tips on making plarn and using it in various projects.
