How to make plastic bag yarn (plarn)
Plastic bag yarn, or plarn, is an eco-friendly way to upcycle plastic bags into something beautiful and useful. It can be used for knitting, crocheting, or crafting. Here is a step-by-step guide on how to make plarn from plastic bags:
Preparing the Plastic Bags:
Start by laying a plastic bag flat on a cutting mat, with the side gussets folded out, forming a rectangle. Using a pair of sharp scissors, cut off the handles and the bottom seam of the bag, recycling the excess plastic. Flatten the bag as much as possible, removing any wrinkles.
Cutting the Strips:
There are two popular methods for cutting the plastic bags into strips: the spiral method and the slit skirt method. For the spiral method, fold the bag in half so that the closed sides are together. Cut upwards from the bottom folded edge, making strips of approximately 1 inch in width. Stop cutting about an inch from the top edge to avoid creating a skinny tube. Once you've made the initial cuts, unfold the bag and cut across to each opposite slit. Continue cutting diagonally from lower slit to upper slit all the way across the bag. This will create a continuous strip of plarn.
The slit skirt method is similar to the process of making T-shirt yarn. Cut across the bag at a diagonal, starting from one of the open ends of the tube. Cut in a continuous strip, working diagonally across the uncut space. This method may result in strips of varying widths, but it is still effective.
Storing the Plarn:
Once you have cut all your bags into strips, it's time to store your plarn. Create a yarn ball by wrapping the end of the plastic yarn around your fingertip and then continuing to wrap it around itself, switching directions every wrap or two. Hold the yarn firmly as it can be slippery, and tuck the end under one of the wraps to secure it.
Now that you have your plarn ready, you can use it for various crafting projects, such as knitting, crocheting, or weaving. Experiment with different colours and patterns to create something unique and eco-friendly!

Weaving patterns with plarn
Plastic bag yarn, or "plarn", is a great way to upcycle plastic bags into something beautiful and useful. It can be woven into various patterns, adding a unique texture that you won't get with regular yarn.
To create your own plarn, start by cutting off the bottom seam of a plastic bag as close to the seam as possible to avoid wasting material. Do the same with the handles. You'll then have a plastic tube, which you can fold in half so that the closed sides are together. Next, cut into the tube on both sides to create the beginning of your plarn. Cut across to each opposite slit, and when you finish one side, turn it over and do the same on the other. When you reach the end, cut the final strip at a diagonal to disconnect it from the bag.
You can weave plarn into various patterns, using a single colour or multiple colours. If you're creating a balanced weaving, your warp will be visible, so choose your foundation accordingly. You can also create a yarn ball with your plarn by wrapping the end of the plarn around your fingertip, then switching directions every wrap or two until you reach the end.
Once you've made your plarn, you can try weaving projects such as a tote bag. Wind your warp and dress the loom for plain weave, then fill your shuttle with plarn as you normally would. Weave the plarn all the way to the end of the loom, or turn back midway, remembering to take your thread under if the thread above goes over the warp, and vice versa. To create handles for a tote bag, use heavier wool yarn, inserting two strands of wool into each of the next three rows.
Plarn is a fun and creative way to recycle plastic bags and create unique woven items. It's an accessible project for all ages and a great way to experiment with different weaving patterns and techniques.

How to make a mini loom
Plastic bag yarn, also known as "plarn", is a great way to upcycle plastic bags into something beautiful and useful. You can weave plastic into paper by making a mini loom using cardboard. Here's how you can make one:
Materials Required:
- Thick cardboard
- Scissors
- Ruler
- Pen/pencil
Step-by-Step Guide:
Step 1:
Start by cutting out a rectangular piece of cardboard that is slightly longer and wider than the size of your desired loom. This will serve as the base of your loom. Mark the centre of the longer sides with a pen or pencil, as this will be where you will be cutting the warp.
Step 2:
Using a ruler, measure and mark several lines across the width of the cardboard, creating a series of evenly spaced parallel lines. These lines will be your guide for the warp threads. Cut along these lines, stopping about 1 inch before you reach the edge of the cardboard. This will create a series of slits for the warp threads to pass through.
Step 3:
Take a plastic bag and cut it into long, continuous strips of equal width. The width of the strips will determine the thickness of your yarn. Unravel the strips to create long plastic threads. You can use a single colour or multiple colours for this step, depending on the desired look of your final product.
Step 4:
Take one of your plastic threads and tie it onto one of the slits at the top of the cardboard, using a single knot. This will be the start of your warp. Continue adding threads to each slit, ensuring that they are all the same length and securely tied.
Step 5:
Now you can begin weaving! Take another plastic thread and start weaving it through the warp threads, going over and under each thread in a alternating pattern. Hold onto the end of the thread gently to avoid snapping, especially if you are using lightweight plastic bags.
Step 6:
You can choose to weave the thread all the way to the end of the loom and back, or turn back midway. If you choose to turn back, pay attention to the thread above: if it goes over the warp, take your thread under, and if it goes under, take your thread over.
Step 7:
When you reach the end of your strip, or if you want to change the colour of your thread, simply tie off the end and cut off any excess. You can continue adding different coloured threads to create patterns and designs.
With these steps, you can create your own mini loom and start weaving plastic into paper, exploring different colours and patterns to create unique and environmentally friendly crafts!

How to weave a basket with plastic bag strips
Plastic bag yarn, or "plarn", is a great way to upcycle plastic bags into something beautiful and useful. Here is a step-by-step guide on how to weave a basket with plastic bag strips.
Step 1: Preparing the Plastic Strips
Start by cutting open the seams of your plastic bags. Cut each bag into long, continuous strips, about 4 inches wide. The wider you cut the strips, the wider your plastic thread will be. You can use a variety of plastic bags, such as grocery bags, potato chip bags, coffee bags, and even candy bar wrappers. Try to get as many colors as you can to add some color to your basket.
Step 2: Creating the Yarn
To create the yarn, take one of your plastic strips and cut it at a diagonal at one end to create a continuous strip. You can then wrap this strip around your finger to create a yarn ball. Switch directions every wrap or two to secure the yarn. Repeat this process for all your plastic strips.
Step 3: Braiding the Yarn
Once you have enough yarn, you can start braiding. Secure the looped ends of your strips over something small and sturdy, like a nail. Divide the strips into pairs, with each strip having a mate. You should have six strands total. Begin braiding, making sure not to braid too tightly or too loosely. A loose braid will result in a floppy foundation, while a tight braid will reduce the texture.
Step 4: Sewing the Basket
When you have 20-30 feet of braided plastic bag, you can start sewing your basket. Coil the rope tightly, skinny side up, until you reach your desired base size. Secure this with a pin or sewing needle. Sew four separate lines into the bottom - one vertical, one horizontal, and two diagonals going through the center. Double the thread and make sure the knot at the end is large enough so it doesn't pull through. Anchor the thread at one edge and push your needle through every other round, keeping the thread taut.
With these steps, you can create a unique and useful basket from plastic bag strips!

How to fuse plastic bag strips into reed shapes
Fusing plastic bag strips into reed shapes is a simple process that requires just a few tools and materials. Here is a step-by-step guide on how to do it:
Materials and Tools:
- Plastic bags (white or any colour)
- Baking parchment paper
- Iron
- Scissors
- Knitting needle or ruler
Step 1: Prepare the Plastic Bags
Start by cutting the handles and the bottom off of six plastic bags. Open up the seams of the bags to create rectangles. You should have 12 sheets of plastic total. If you want a particular colour palette, choose bags with the desired colours. White bags can also be used as a base to mix with other colours to create lighter tones.
Step 2: Stack and Fuse the Layers
Place a sheet of parchment paper on a heat-resistant surface, such as an ironing board. Stack nine plastic sheets on top of the parchment paper. Set aside the remaining three sheets for now. Cut any extra bits and trim off any threads that are not fully intact. Then, place another sheet of parchment paper on top of the stack.
Step 3: Iron the Layers
Preheat your iron to the polyester setting. This temperature should be hot enough to fuse the plastic without melting it. Iron over the top sheet of parchment paper, constantly moving the iron. Do not let the iron touch the plastic directly. You can also experiment with different iron temperatures to find the setting that works best for fusing without melting.
Step 4: Add More Layers
After the first two bags are completely fused, add the third bag in the same way as the second. Fuse the third bag and let it cool for a few seconds. You can now decorate your fused plastic with appliques or add colour by sprinkling grated crayons between the layers.
Step 5: Form Tubes and Reeds
Cut the fused plastic into strips. Wrap a knitting needle or ruler with the strips to form tubes. Be careful when handling the plastic, as too much heat can cause it to wrinkle or melt. Experiment with different forms to make reeds, such as using a ruler or metal strips of different widths.
With these steps, you can create fused plastic bag strips in reed shapes, which can then be woven into various projects, such as baskets or bags.
