I've been scouring my stash for any undyed yarns I might have. I've found quite a few, but these nine are the ones I think I'll bring with me to dye.
A few years ago, I signed up for a yarn CSA out of Martha's Vineyard, which has since relocated to Virginia as Juniper Moon Farm. At the end of the season, I got two skeins of Romney and four skeins of Corriedale.
Coffelt's Farm from the island, and I've carried them with me a long time, and a long way. While I know these are wool, I'm not sure from which breed, and the website doesn't mention which breed they use for the wool, though there are Romney, Dorset, Coopworth, and Texal on the farm.
Sunny Knoll Farm in New Hampshire. I don't know much about this yarn, only that I've been told that alpaca accepts dye beautifully, and that it will look good when done.
I will continue to look through my stash to see if I have other undyed skeins of yarn. I know that I have a few skeins of Cascade Epiphany, a discontinued line, in a mustard yellow. Mirabel tells me that this can be overdyed, and if I can find it, I'll bring it with me. I only bought it because the yarn had been discontinued and I knew that when my LYS was soldout, it would be out of reach forever.
