I returned from Toronto with a couple of pair of worn out socks. One pair was beyond salvation. The holes in the foot and heel were too large to repair. I’ll save the legs and knit new feet, I thought, but there was so much lint embedded in the yarn I knew I’d never be able to restore the legs to a wearable condition. That pair got trashed.
The second pair, on the other hand, had possibilities: one sock had a hole in the toe and both heels were worn through, but the main part of the foot wasn’t worn too badly. So I cut out the heels and removed the cast-off toe portion of both socks and started to work. I knit new heels and toes and those socks are now just like new!
