A good use for all of my extra yarn – at least, 100% wool yarn that isn’t super wash . . . I hand-wound different sized balls of yarn, then put them in old pairs of panty hose and tied knots in between, so that they wouldn’t unwind or move around at all.
Surprisingly, it took three times in a hot washer and hot dryer before they felted enough to hold together. These are all too big to string together, but if I made smaller ones, I could use a large needle and string them into holiday garlands.
