Hey everyone, and welcome to my corner of the web where we talk all things yarn—no boring industry jargon, promise. I’m the guy behind that small sustainable yarns supplier you might’ve stumbled on at a craft fair or seen popping up on your Instagram feed, and today we’re breaking down exactly how the yarns I send out to makers, knitters, and small-batch brands actually get made. A lot of folks assume “sustainable” just means “pretty colors” or “cheap for the planet,” but there’s a whole process that goes into every spool, one that’s way more hands-on and intentional than the fast fashion or mass-produced yarn you might grab at a big-box store. Let’s dive in, yeah? Sustainable Yarns
First off, let’s get one thing straight: sustainable yarn isn’t just one type of fiber cranked out the same old way. The starting point is everything—this is where most of the real work happens, before any spinning machine even gets turned on. I don’t mess with synthetic fibers at all for my line, because polyester, nylon, and acrylic don’t biodegrade (we’re talking hundreds of years to break down, if they ever do, and they shed microplastics every time you wash something made with them). Instead, I stick to natural, regenerative fibers, and sometimes even upcycled materials that would’ve otherwise gone to landfill. Let’s start with the most common ones I use, because these are the workhorses of the sustainable yarn world, and each has its own specific process.
Wool is the big one, but not just any wool. I work with small family farms across the Pacific Northwest and parts of Europe that practice regenerative agriculture. Regenerative isn’t just “organic” (though a lot of their land is certified organic)—it means they’re actually putting more back into the land than they take. For sheep, that means rotational grazing: moving flocks to different pastures every few days so the grass has time to regrow, instead of overgrazing which strips the soil and leads to erosion. The sheep are raised without any routine antibiotics unless they’re sick, no growth hormones, and they have room to roam—you can taste (well, not taste, but you can feel the difference) in the wool. When it’s time to shear the sheep, the shearers are trained to do it quickly and gently, no stress for the animals, which is way different from the factory shearers you might hear about. Once the fleece is shorn, it’s not rushed to a big processing plant right away. The farms sort it by hand first, pulling out any dirty bits, grass seeds, or damaged fibers—no fancy machines here, just real people who know their sheep and their fleeces. That cuts down on waste before it even gets to the next step, which is scouring.
Scouring is the part most people don’t talk about, and it’s where a lot of sustainability gets messed up if it’s done wrong. Traditional scouring uses tons of hot water and harsh chemicals to get the lanolin, dirt, and grease out of the wool. But the farms I work with use a closed-loop scouring system. That means the water is reused over and over, filtered to remove the lanolin and debris, and even the lanolin is collected to make skincare products—so nothing goes down the drain. The chemicals they do use are non-toxic, biodegradable, and way gentler on the environment. The wool gets rinsed multiple times with that same filtered water, so by the end, it’s clean, soft, and ready to be dried. No gas-guzzling industrial dryers here either—most of the time, it’s air-dried in the sun or large, energy-efficient drying sheds that run on solar power the farms have installed.
Next up: cotton. A lot of people assume cotton is sustainable because it’s natural, but conventional cotton is actually one of the most pesticide-heavy crops in the world. The farms I partner with grow organic cotton, and even better, a lot of them use regenerative cotton practices too—crop rotation with legumes that fix nitrogen in the soil, so they don’t have to use synthetic fertilizers. They use natural pest control, like ladybugs to eat aphids instead of toxic sprays, and they collect rainwater to irrigate the fields, cutting down on their water use by like 70% compared to conventional cotton farms. When the cotton is harvested, it’s ginned (that’s the part where you separate the cotton fibers from the seeds) with small, energy-efficient gins, not the huge ones that waste tons of fiber and use too much fuel. Then it’s sorted by hand again to remove any impurities, same as the wool, before moving on to carding.
Wait, what about upcycled yarn? That’s my favorite, tbh—taking something that would’ve been thrown away and turning it into a new, usable yarn. I have a whole line of upcycled yarn made from old t-shirts, bed linens, even vintage clothing that people donate or send to me when they don’t want them anymore. The process for upcycled is a little different, because we’re starting with existing fabric, not raw fiber. First, we sort through all the donations to make sure they’re clean, not stained, and made of natural fabric (no synthetic blends, because those don’t spin well into yarn and they’re not truly sustainable). Then we cut them into long, thin strips—no fraying, and we make sure the strips are consistent so the yarn is even. Sometimes we mix different fabrics, like cotton t-shirts and linen bed linens, to get unique textures, but we never mix synthetics. That’s important—you want the whole yarn to be biodegradable when it’s eventually at the end of its life.
Now, the part everyone sees: spinning. Spinning is where the raw fiber (or the fabric strips, for upcycled) gets twisted together into the yarn we all know and love. But not all spinning is equal. I use small, ring spinning machines that run on electricity from renewable energy, not the old water-powered mills or huge industrial spinners that waste fiber and use way more energy. The key here is the twist: we adjust how much we twist the fibers to get the right thickness and texture. For a soft, drapey sock yarn, we use a little less twist, and for a sturdy, warm blanket yarn, we use a little more. No over-twisting that makes the yarn brittle, no under-twisting that makes it shed. And for upcycled strips, we have to be extra careful with the twist because the fabric can stretch or break if it’s twisted too tight. We also only spin in small batches, so we can control the quality—if a batch of wool is a little thinner or softer than usual, we note it and don’t mix it with a different batch that’s too different, which keeps everything consistent for the knitters.
Wait, we can’t skip the dyeing part, right? Because half the fun of yarn is the colors. But conventional dyeing is another huge polluter—they use tons of water, synthetic dyes that have toxic chemicals, and most of that water gets dumped back into rivers or groundwater with no treatment. That’s a big no for me. All my yarns are dyed with natural dyes, and even better, I use a zero-waste dyeing process. The natural dyes I use come from things like indigo (plants, not the synthetic stuff), walnut hulls, onion skins, elderberries, even coffee grounds—all plant-based, biodegradable, and non-toxic. The dye bath is made with that same closed-loop system: any unused dye is filtered and reused for the next batch, no water wasted. We also don’t use harsh mordants (the stuff that makes dye stick to fiber) like formaldehyde or copper. Instead, we use natural mordants like alum, which is a mineral salt, or even iron, which is non-toxic and comes from natural sources. The water used for dyeing is filtered, tested, and then either reused for the next scouring or dye bath, or treated to meet local water quality standards before it’s released. I also test every batch of dyed yarn to make sure the color is lightfast—meaning it doesn’t fade in sunlight or wash out easily—so knitters don’t end up with a project that fades after a few uses. That’s a big plus, because it means your sustainable yarn project will last longer, which is part of being sustainable too.
Once the yarn is spun and dyed, we wind it into skeins or balls, right? But again, no fancy machines that waste yarn. We use hand-operated or low-energy winding machines that don’t pull the yarn too tight, which can make it hard to knit with. We also add small tags to each skein that tell you exactly where the fiber came from—like which farm the wool was from, what kind of crop the cotton was, even the date it was dyed. That transparency is huge for me, because I want my customers to know exactly where their yarn came from, not just a vague “sustainable” label. And we make sure every skein is the exact weight and length it says it is, no skimping on yardage, which is another thing I hate about mass-produced yarn that often cuts corners on weight to save money.
Wait, let’s talk about the end of the life of the yarn too, because sustainable isn’t just about how it’s made—it’s about what happens when you’re done with it. All my yarns are 100% biodegradable, right? Wool, cotton, linen, even the upcycled t-shirt yarn—they’ll break down in a compost pile in like a year or two, no microplastics left behind. I also encourage people to mend their projects instead of throwing them away, or to donate them when they’re done, so they get used again, instead of ending up in a landfill. That’s part of the sustainable process too—making products that last, and are easy to dispose of responsibly when they’re done.
I know a lot of people ask me why this process is more expensive than regular mass-produced yarn. The short answer is: because it’s not cut corners. When you’re working with small farms, hand-sorting, closed-loop systems, natural dyes, and renewable energy, it costs more than cranking out thousands of skeins in a factory with harsh chemicals, fast processing, and cheap synthetic fibers. But the long answer is: you’re not just paying for yarn, you’re paying for farmers who get fair wages, less pollution, no microplastics going into the environment, and a product that’s actually good for the planet, not just marketed as good. I work really hard to keep my prices as fair as possible while still paying my suppliers and workers a living wage, because sustainability shouldn’t mean exploiting people or the planet.
If you made it this far, thanks for hanging out—this is the stuff I love talking about, because it’s not just about yarn, it’s about making small, intentional choices that add up to something bigger. Whether you’re a hobby knitter making a scarf, a small brand making ethical clothing, or someone who just cares about what you put into your projects, my sustainable yarns are made with care at every step, from the sheep in the pasture to the skein in your hands.
If you’re a maker, brand, or someone looking to stock sustainable yarns for your shop, I’d love to chat. We can talk about custom dyed batches, bulk orders, or even upcycled yarn tailored to your needs. Shoot me a message anytime, and we can figure out what works for you and for the planet.
