What Is Plarn Yarn?

Plarn yarn (AKA plastic yarn) is a synthetic fiber made from plastic shopping bags! This fiber isn’t popular because it’s hard to find and you have to make it yourself. Unlike marled yarn which is readily available in stores. However, it’s more durable, long-lasting, and water-resistant than regular yarn.

They’re a type of novelty yarn and are great for making fun household projects. Only wind by hand as it’s not suitable to use with any winding machines like a swift. For more information on uses of a swift here’s my guide.

Where It Comes From

Plarn yarn is made by cutting plastic bags into strips and then crocheting or knitting them together. You can braid the strips to make a thicker rope-like yarn, similar to how t-shirt yarn looks.

How To Wash Plarn Yarn

Here are the care instructions for plarn fibers.

  • Rinse them in cool water
  • Line dry them, don’t lay flat
  • Don’t iron, bleach, machine dry or wash them

They’re made of plastic materials, so don’t treat them like traditional yarn!

What Do You Use It For?

Wondering whether you should use it to make a project? It’s often used for projects and things like baskets, coasters, beach bags, purses, rugs, mats, toys, crochet items and other crafts. For a fun, useful object, make plarn and knit a container for holding plastic bags! Some other ideas are placemats and bathmats.

Totes for vegetables, water bottle holders are other ideas. I don’t recommend it for projects that need to be flexible since it’s a stiff yarn. Don’t use it for clothes, either!

Where To Find It

While you can find plastic bag yarn in some stores, it’s rare. The best part of using it is making plastic bag yarn yourself! So find some plastic grocery bags you have lying around the house, or ask friends or family if they can spare some.

Get making! Here’s how to make it.

  • Clean the bag first
  • Ensure there’s nothing in it
  • Lay it flat and fold it in half lengthwise
  • Fold it in half again
  • Cut the folded bag into plastic loops
  • Discard the handles and bottom
  • Repeat for as many plastic bags you have
  • Knot the loops together
  • You’ve made your first plarn ball!

Or, use the slit skirt method to create one long continuous strand from one bag.

Here is a video tutorial by Life on Leetown on how to make it. 

This helpful guide will walk you through the process of cutting up plastic bags in strips.

Here is a video tutorial by Jenny Guldin on the spiral cut method to create a single strand of plastic so there’s no joining pieces. 

The information in this video on the one long strand method for creating plarn will be a great help!

  1. I used to make tote bags from grocery bags. Now, most of the grocery bags are biodegradable so they do not last like the old ones did. Just an observation about using them for the sleeping mats for homeless–they are cold, stiff, and noisy to lay on.

    • Thanks so much Shar for sharing your experience with biodegradable grocery bags, that’s very helpful. They are good points you raise regarding the sleeping mats. Cheers Jodie
