As a Sock Knitter (capitalization for emphasis), I love to find new sock yarns that are vegan. I know that for beginning knitters, this can be tricky. So, for a while I've been working on a master list of vegan yarn made specifically for socks. I've finally gotten it to a posting stage so you'll see that I've put a link on the upper left sidebar of my blog. I will also link to it here for you blog aggregator readers.
As it stands, the list describes first the commercially-available yarns with names, fiber content, and links to the manufacturer's page about the yarn and a link to the yarn page on Ravelry. Then the same for indie dyers and spinners.
I would love to add at least one photo for each yarn, along with links to projects and reviews. If you have made socks with these yarns and would like me to link to a photo, review, or blog post featuring completed socks made with this yarn, please comment or e-mail me. Otherwise, I'll have to pop around the internet looking for ones to link to.
Also, if you are an indie dyer/spinner who deals with vegan sock yarns, please contact me and I'll add you to my list. Same goes for if I've left a commercial yarn off the list.
I hope this list is useful and please let me know if you have any ideas for improving it!
