undid my knitting. All those little knots that you make one after another, row by row, to knit a sock, I undid them. It's easy. Take the needles out, a little tug and they just fall apart. One after another, row by row. I undid the extra heel and then I just kept going. The foot, the first heel, the ribbing of the leg. All those loops unraveling themselves as you pull the wool. Then there was nothing left to unravel, only a pile of crinkled blue wool in my lap.
