If you've got a stash of plastic bags tucked away in a kitchen cupboard, you might want to try crocheting with plarn to finally put them to good use. It's one of those hobbies that feels double-productive because you're not just making something cool, you're also literally clearing out clutter and keeping plastic out of the landfill. Most of us have that "bag of bags" hanging on the pantry door, and honestly, there are only so many times you can reuse them for small trash cans before they start taking over your life.
Plarn, for those who haven't heard the term before, is just a portmanteau for "plastic yarn." It sounds a bit fancy, but it's really just strips of polyethylene bags looped together to create a continuous strand. Once you get the hang of it, you can treat it almost exactly like bulky weight yarn. However, there are a few quirks to the process that are worth knowing before you dive in headfirst with your favorite crochet hook.
Getting your materials ready
The first step isn't actually crocheting; it's processing. You can't just start stitching a whole bag. You need to turn those crinkly heaps into something workable. I usually suggest sorting your bags by thickness first. Those super thin ones from the produce section don't mix well with the heavy-duty ones from the department store. If you mix them, your "yarn" thickness will be all over the place, and your project will look a bit lumpy.
To make the plarn, lay a bag out flat, snip off the handles and the bottom seam, and then cut the remaining tube into loops. The width of your strips depends on how thick you want your yarn to be. For standard grocery bags, two-inch strips are usually the sweet spot. Once you have a pile of loops, you connect them using a simple lark's head knot—basically, you loop one through the other and pull. It creates a small knot, but don't worry, those knots mostly disappear into the texture of the crochet stitches.
Picking the right hook
When you're crocheting with plarn, your choice of hook is going to make or break your experience. Forget your tiny steel hooks or even your standard 5mm ones. Plastic doesn't have any "give" or stretch like wool or cotton does. If you try to use a hook that's too small, you're going to be fighting the material every single step of the way, and your hands will be cramping up within ten minutes.
Most people find that a large hook—something in the 8mm to 12mm range (Size L, M, or N/P)—works best. Plastic is bulky and a bit sticky. A larger hook creates a looser fabric, which is much easier to work with. If you happen to have a plastic or bamboo hook, those often work a bit better than aluminum because the plarn slides over them with a little less friction. If you find the plastic is dragging too much, a tiny bit of unscented lotion on your hands or even a quick wipe of the hook with wax paper can help things glide more smoothly.
Why the tension matters
One of the biggest hurdles when you start out is managing your tension. We're usually taught to keep our stitches nice and even, but with plarn, you have to be a bit more relaxed. Because plastic doesn't stretch, if you pull your stitches too tight, you'll find it nearly impossible to insert your hook into the next row. It becomes like trying to crochet with zip ties.
It's better to aim for a slightly "floppy" feel while you're working. As the piece grows, the structure of the plastic will give it plenty of sturdiness. If you're making something like a doormat or a sturdy basket, you might be tempted to pull tight for strength, but trust me, the material is strong enough on its own. Keep it loose, keep it comfy, and your wrists will thank you later.
Great starter projects for plarn
So, what do you actually make with this stuff? You probably don't want a plarn sweater (it would be incredibly hot and loud), but for anything that needs to be durable and waterproof, it's perfect.
- Outdoor Doormats: This is the classic plarn project. Since it's plastic, it doesn't rot when it gets wet. You can hose it off when it gets muddy, and it'll dry in no time. Plus, the texture is great for scraping dirt off shoes.
- Market Totes: There's something very satisfying about turning dozens of single-use plastic bags into one sturdy, reusable bag. These are incredibly strong. You can haul heavy jars or produce without worrying about the bottom blowing out.
- Shower Caddies: Since it's waterproof, plarn is great for little baskets to hold shampoo and soap in the dorms or even at home. It won't get moldy like cotton might.
- Sleeping Mats: In many communities, volunteers spend hours crocheting with plarn to create sleeping mats for people experiencing homelessness. These mats are lightweight, provide a barrier against the cold ground, and don't attract bugs. It's a pretty amazing way to use your skills for a good cause.
Dealing with the sensory stuff
I'll be honest: crocheting with plarn is a different sensory experience. It makes a crinkling sound the whole time you're working. If you're watching TV while you crochet, you might need to turn the volume up a notch. Also, some people find the smell of the plastic a bit much if they're working with a huge pile of bags, though usually, it's not an issue unless the bags were stored somewhere damp.
The most important thing to watch out for is your hands. Plastic is much more abrasive than traditional yarn. It can actually cause little blisters if you're doing a marathon session. I usually recommend working on plarn projects in shorter bursts. Do a few rows, then go do something else. It's a bit of a workout for your fingers, so don't push it if you start feeling a dull ache.
Color coordination (or lack thereof)
You might think that crocheting with plarn means you're stuck with a muddy gray or white mess, but that's not necessarily true. If you start paying attention to the bags you get, you'll see a whole rainbow. Target has those iconic red-print bags, some grocery stores use bright blue or yellow, and newspaper delivery bags are often a vibrant orange or green.
If you sort your bags by color before you start making your yarn, you can actually create stripes or patterns. Even if you just have the standard white bags, you can mix in a few colored ones to get a "sprinkles" effect. On the other hand, there's a certain charm to the "scrappy" look where you just tie the loops together as they come. It tells a story of all the different places you've shopped.
Keeping it clean
One of the best perks of anything made from plarn is how easy it is to clean. You don't have to worry about delicate cycles or specialized wool wash. Most plarn items can just be rinsed off with a hose or wiped down with a damp cloth. If you've made a bag and it gets something spilled in it, just dunk it in some soapy water, rinse it, and hang it to dry. Just avoid the dryer—high heat and plastic are a recipe for a melted disaster.
It's also surprisingly durable. Unlike fabric bags that might fray or get holes over time, plastic holds up against a lot of friction. A well-made plarn rug can live on a porch for years before it starts showing any real signs of wear and tear.
A few final thoughts
If you've been on the fence about trying this, I'd say just go for it. You don't have to go out and buy anything new; you likely have everything you need sitting in your kitchen right now. It's a low-stakes way to practice new stitches or just keep your hands busy while you're listening to a podcast.
Crocheting with plarn might feel a little weird at first—the texture is different, the sound is different, and the "yarn" looks like trash—but that's the beauty of it. You're taking something that was literally designed to be thrown away and turning it into something functional and long-lasting. It's a small way to be a bit more mindful about waste, and at the end of the day, you get a cool new bag or mat out of the deal. Plus, your pantry door will finally be able to close again without a landslide of plastic bags falling on your head.
