Mill Ends yarn - 1 lb
These are the ends of bobbins that I plyed together into 3-ply yarns. They are mismatched with knots and likely plenty of wonky spots. But it is cheap!
This yarn has not been soaked after plying so could use a good soaking before you work with it. To soak, do just as you would do with a finished object. Luke warm water with a little wool wash for 15 minutes for so. Hang to dry.
