Today we're seeing huge, and vitally important, global youth led protests for action on climate change. There's so much of the narrative around sustainability that focuses on small individual changes, in a way that I can't help feeling is engineered to detract from the level of major change required from big business and government. At the same time so much of the zero waste movement is so elitist, and weirdly focused on buying new stuff instead of using up what you have. But... trying to reduce our impact, as individuals, and as a business, has to help. Here are a few notes on things we do, and that we could do better (although I'm sure there are lots of other ways I haven't included here). I'd love your input. 


A lot of our packaging decisions are based on keeping shipping costs as low as possible, and reducing the risk of anything arriving with you damaged. Both of those things are also good for sustainability: lighter packages are cheaper to ship and use less fuel and reducing waste of anything is positive.

Mailing bags

Our first choice for shipping yarn is biodegradable mailing bags. These protect the yarn better than paper / cardboard, and are the lightest option we've found. They're fully recyclable and biodegradable. You can also easily reuse them, although if you want to I'd recommend doing so quickly — they do have a shelf life!

Cardboard boxes

For heavier, bulkier items or mixed orders we tend to use cardboard boxes. We order many of our cardboard boxes in custom sizes, to perfectly suit certain products, both in terms of size and strength. This means we don’t need to use extra materials to bulk out the package and things like books aren’t shifting around and getting damaged. It also means that the overall package is the lowest possible size and weight for shipping. The boxes can be recycled and should arrive with you in a state where they can be reused multiple times.

Book wraps 

We ship smaller book orders in specially designed book wraps produced by a climate neutral company. These are made from a combination of recycled paper and FSC certified wood. They can be recycled and help to prevent damage to (and therefore waste)  books.

Packaging improvements

In terms of packing materials there are a couple of areas that I’d really like to improve. The big ones are bubble wrap and clear plastic bags. We’ve recently found a source of biodegradable bubble wrap which we’ll be switching to when our current roll runs out (nothing sustainable in not using what we already have!). Most of the bubble wrap we use is to protect hardback books — much as I personally love hardbacks I’m definitely pro paperback in terms of shipping. They’re less likely to get damaged, weigh significantly less so fuel consumption and shipping costs are lower, and they need less packaging.

The clear plastic bags are tricky. Most of the yarn we receive from suppliers arrives in bags, and it’s hard to see an alternative that would work at scale. We stock 136 colours of Finull PT2, being able to see what’s in each bag on a shelf makes a huge difference in a warehouse environment. We also use clear grip bags to package our yarn packs and kits. These are recyclable, but most plastic recycling in the UK is shipped overseas and extremely problematic. Being able to see what’s in a kit at a glance helps us to reduce shipping errors and reduces labelling requirements. I hope that people reuse these bags, but I would like to replace them with an alternative that functions as well. There are some biodegradable options available but the shelf life is an issue! We don’t want them to fail if we, or customers, use them for longer term storage. 


Most of our yarns are 100% wool, and we aim to stock a high percentage of yarns using wool that might not have a market if it weren’t for hand knitting. We also intentionally choose to stock yarns that will make garments you can wear for years, mend, and hand-down. There’s a lot of conflicting information out there about the sustainability of wool farming, and a lot that depends on individual practice, but be aware that the leader of recent campaigns against wool has been PETA, an extremely biased organisation. I'd view anyone trying to convince you that petrochemical based fibres are more sustainable than wool with extreme skepticism.

The only wool wash we sell is a solid bar with plastic-free packaging. We don’t have any desire to ship liquids, they’re heavy, often restricted by customs, and can leak. Although it’s obviously not something we can do while we’re online only I’d love to see physical yarn stores do bulk refills of liquid wool wash — does anyone know of a store doing that?

In the studio


Wool moths are a huge problem in Edinburgh, and are apparently on the increase throughout the UK. We obviously take the risk of damage to stock, or of sending you something that could hurt your stash, very seriously. We switched from pesticides to using a natural option — tiny parasitic wasps that eat the wool moth eggs. These are the size of specks of dust, so much less scary than “parasitic wasps” sounds, come on small cards that we just place throughout our yarn shelving so there’s nothing to contaminate the yarn or air, and we’ve found them really effective. The supplier we used seems to have stopped shipping to the UK (thanks Brexit) but if you’re looking to try this here’s a UK store https://www.dragonfli.co.uk/products/clothes-moth-egg-killer-trichogramma-evanescens

Reusing and recycling

Where possible we reuse packaging we receive. Things like bubble wrap and paper we reuse ourselves. We don’t usually have a use for things like packing peanuts and those big air pillows but the clay studio across the hallway loves them. Packing materials we can’t reuse, like the giant boxes yarn comes in, our recyclable general office waste, and surplus or damaged books are recycled by a local charity. On a micro level Bex composts our coffee grinds and food waste.

Office supplies

We use recycled, recyclable and biodegradeable options as much as possible and we're always trying to reduce how much paper we use and find better alternatives.


We're located in a building with shared utilities so we don't have as much control as I'd like, but reducing our energy consumption, especially from computers and dyeing, is something we're working on. One reason for our current location, and that I'd want to prioritise if we ever moved, is that it allows everyone in our team to commute by bus, bike or walking — being further out of the city would certainly be cheaper but that would be a major disadvantage.


This might be the hardest thing to write about, and one that might not seem like it has much to do with sustainability. However, the reality is that most businesses selling stuff succeed by convincing you to buy more stuff than you need, using manipulative tactics. This is an incredibly unprofitable industry (in comparison to others), and it's very seasonable, just selling enough to break even and maintain cash flow is really challenging so there's a lot of pressure to market in the most effective ways. There are bigger questions, and decisions there for us, especially as Brexit looms. But I see so much of the knitting industry relying on marketing in a way that manipulates your fear of missing out on stuff, or that you have to be seen with certain yarns or project bags to be respected, or that being part of a community relies on sharing the stuff you've bought, and it's both incredibly non-inclusive and unsustainable.

I don't know if we always manage to balance marketing in a way that lets people know about the cool stuff we have that they might want, and that they might want to buy from a small independent business rather than a VC funded multinational, with not manipulating people into buying stuff they didn't really want or need, but it's definitely a goal. I'm never going to judge anyone for enjoying the creative resource of a large stash, or the inspiration of full bookshelves, but I hope you truly enjoy and use the things you buy from us.
