Last May 15th my sister-in-law slipped on her basement stairs and clunked down the three remaining steps on her left heel. Her heel was shattered. The surgery went well and the bone, with the help of plenty of titanium, healed. Unfortunately, a sore and subsequent hole/wound from wearing a special boot did not close up.
I lost count of the various surgeries she’s undergone and had to wear a wound vac for several weeks. During this time, she was still teaching and wore the pair of slippers I knit for her to school as she needed to keep her foot covered and warm.
…and an acrylic yarn held together for the seamless slippers.
