Don’t Forget Secondhand!
Thrifting is wonderfully sustainable and also a good way to ensure you’re not supporting unethical practices.
Here are our favorite places to buy secondhand clothing.
Knit Your Own
Knitting is a fun and fulfilling project, and you can make exactly what you want!
One of the best things you can do is to source local wool from sustainable and responsible farms or local yarn stores. It’s a wonderful way to support small businesses and oftentimes you can even visit the farms. Check if there is a Fibershed near you where many farmers also use regenerative practices.
We also have a roundup of sustainable fabric and yarn stores!
Wool and the Gang
Wool and the Gang is great if you’re looking for cute and trendy styles, with everything you need to make your own sweater!
Some of their yarns are definitely better than others, and for sustainability and ethics we’d recommend sticking with their upcycled or organic cotton and hemp blend yarns.
Andrea Dekrout
I would love you to check out the knotty ones https://www.theknottyones.com . I had their heartbreaker sweater and tommy cardigan for years they get a ton of ware and still look good. Many are hand knitted by woman knitters who get fair pay for excellent work, all their wool is cruelty free and Oka-tec certified and their cotton is organic. I don’t know them, this message is not in any way from them. I am just an impressed customer who thinks this company is really trying on all fronts and I don’t see their name out there very much. Also I am a big fan of you so I am connecting two things I really like.
