Two Sweaters for my Father:
A collection of Perri's essays from Knitter's Magazine and other publications including the New York Times.
"I still write about the medical world. But to my unending delight, I have also been able to write about knitting, the endlessly interesting and
endlessly complex questions of how our brains and fingers work together, how we move through our lives with yarn and needles, how knitting shapes and
colors our days and our daydreams."
