Well well well. Learn something new every day. Who'd have thought of spinning thread and making yarn from milk proteins? Well, if someone can spin yarn from cat hair I suppose milk yarn isn't that odd.
We'll see how things go with the prayer shawl thing. I was told there's no wrong way to do it, yet at the same time the shawls have to be up to certain standards (of softness and sturdiness). Red Heart Super Saver yarn just isn't soft enough to use for these prayer shawls; Lion Brand Homespun or Caron Simply Soft or Red Heart Soft are better yarns to use. Hmmm.
