There's some good news, though. Apparently there are other knitter/designers out there who feel the same way I do and who've made a deliberate decision not to treat their wool products. Here's a short list:
1. Jared Flood (aka Brooklyn Tweed) has put out two newish yarns, "Shelter" and "Loft". I have some of each in my stash and they're absolutely gorgeous to work with.
2. Veronik Avery's St. Denis line of yarns comes in a ton of beautiful colours. You can double-strand the Nordique to create heavier garments.
3. My recent discovery in this area is Quince & Co. I think I'm in love with the colours, the beautiful photography, and the wide range of yarn weights.
