Worsted-weight wool yarn naturally dyed with black walnut hulls. I forage the nuts while the hulls are still green in northern Wisconsin. To remove the hull from a nut (we dry those to eat), I thwack it with a rock and pull it from the nutshell. To make the dye, I simmer hulls slowly in an antique iron pot and let it cool in the pot overnight. Then I filter the dyebath into a slow cooker and add yarn. Low heat and slow cooking produce rich color.
See more plant-dyed yarns at https://www.etsy.com/shop/DonnaKallnerFiberArt?section_id=14425260 . Or to simplify shopping, use the "Search Items" box at the top of the main shop page (https://www.etsy.com/shop/DonnaKallnerFiberArt) to narrow down choices to one weight of yarn (I generally sell fingering, worsted and bulky). You can also use that search box to shop skeins of a particular color or plant dye (indigo, walnut, goldenrod, willow,hops, etc.) If you're selecting skeins for a particular project and would like to see a snapshot of the skeins together, please send me a convo with the product numbers in the titles.
