I decided to get out of my comfort zone and try something new, like darning a sock. This pair of wool socks was over 20 years old and still in good condition. No hole in toes or heels but there was a big one near the cuff.
I used 2-ply mohair/silk yarn in similar color and a bottle for support. It was much faster than I thought, taking less than 10 min and my sock was fixed!
It feels so good to learn a new skill, thanks
permie!
