&quot;I started by knitting a small hat in hopes of practicing before trying to knit a larger hat,&quot; Sansonetti says. &quot;It turned out pretty well, and by chance was the perfect size for a newborn.&quot; The doctor decided to give the practice cap to the next baby he delivered. He recalls the look of surprise and delight on the mother&#039;s face, which he says prompted him to knit more miniature hats.
