I will always suggest you stash dive first, shop local and/or online with small businesses.
The 1764 Shepherdess shop sales support the Maker’s Meetup zoom licensing, #spin15aday events, #campspin15 and the website.
Currently available are rovings of Corriedale, Falkland, Manx Loaghtan, natural BFL and Polwarth/Silk. I also kettle dyed Romney locks sourced in Washington State in a Pacific Northwest color way to play with.
