How does this align with my curriculum?
This is the first part of a two-part activity on recycling yarn.

Duration:
10 minutes (may take longer depending on how much yarn you have).
What You Need
- Scrap yarn. Chunky yarns work best, but other types could be used
- You can also use yarn from an old garment, such as a sweater or a pair of socks
- Pair of scissors
- Stiff-bristle hair brush or dog brush
What To Do
Get inspired by these people who are also recycling fibres!
If you are starting with a finished knit object, you will need to carefully unpick the stitches until you have a strand of yarn.
If you have a ball of yarn, unwind it until you have a single strand of yarn.
Cut the yarn into 15 cm-long pieces (it does not need to be exact)
Pull apart or unply the yarn. Plies are the single strands of fibre that are twisted together to make yarn.
Did you know?
Most yarns are made by plying two or three strands together. You will learn all about this in Recycling Yarn Part 2: Spinning.
Take a handful of fibres and hold them at one end. Hold the brush in your other hand.
Brush the yarn as you would brush your hair.
Don’t worry if fibres get stuck in the brush.
Continue brushing the fibres until it no longer looks like yarn.
It should look like long, soft fibres.
Lay the fibres down on a flat surface, such as your lap.
Pull the fibres out of the brush. Try to keep the fibres facing the same way.
Lay these fibres beside the other fibres.
Continue to add fibres until you have several good-sizes handfuls.
Lay out the fibres side-by-side.
Roll up the fibres width-wise.
Once the fibre is all in a nice roll, you are done. This type of a roll of fibres is known in spinning as a rolag.
Once you have a rolag, you can spin these fibres into yarn. To learn how to do this, check out the Recycling Yarn Part 2: Spinning activity.
This activity is a part of our new project launching fall 2021 - Clothing4Climate
The project will help youth understand the impact of fast fashion on climate change and provide youth with tools to reduce their consumption and extend the life of their clothing!

Yarn is a long continuous length of interlocked fibres. By pulling the yarn apart, you are taking the fibres back to the state they were in before they were made into yarn.
Fibres that come from plants and animals, such wool, apaca, cotton, and linen, are relatively short. They are a lot like the fibres you made. They also tend to be kinky, much like curly hair. You can see this in the closeup of the thread made of wool below. Each of the little hair-like strands is a fibre of wool.
The shape of these fibres lets them hook onto each other. This is why they are good for making yarn.
However, most of the yarns we use are not made from natural sources. They are often made from synthetic materials such as polyester, polypropylene, and acrylic. These yarns are not made from short fibres. Instead we make these yarns by twisting together long filaments of the material. The material is first melted into a liquid. The filaments are then made by pushing this liquid through narrow tubes. These tubes are called spinnerets. When the liquid cools, it forms a thread. Synthetic threads are more durable than threads made from natural fibres.
Did you know?
The word “spinneret” comes from the silk-spinning organ of a spider or insect.
Synthetic fibres can be made in any colour. They can also be stretchy, and can be designed to have other characteristics that people want. Most synthetic fibres are very long, which is why the yarn was cut in this activity. Other synthetic yarns are made from short fibres. This is so that they feel and act more like yarns made from natural fibres.
It is not uncommon for knit garments to get holes in them. These holes can often be repaired by someone who knows about knitting. But for those who do not, the garment will likely be thrown away. Instead of ending up in a landfill, the fibres from these garments can be recycled. Whole new garments and other things can be made from them!
Some companies are creating businesses around doing just that. For example, Loops & Threads® yarns are partly made from recycled plastic.

- Unply a longer piece of yarn. Are the fibres made from long single filaments, or short filaments?
- Make your own blend of yarn by using fibres from a variety of yarns. Swap some with a friend to make a custom blend that you can share.
- Try brushing out different types of yarns. Which is easiest to work with?
- Thick chunks of fibre like the ones made here can add interesting texture to weaving projects.
- It is also possible to donate leftover yarn. Find out which charities or organizations near you will accept yarn.
