Strange Horizons Fiction: The Leaving Sweater, by Ruth Nestvold:

The leaving sweater was made of scraps of leftover red wool—many different shades of red. And many different qualities of yarn, from mohair to raw silk to cotton and linen mixes. And many different stitches, from ribbed to open work to waterfall to butterfly. Although it had been a decade now, Vicky could still remember watching her mother make it as a present for Vicky's high school graduation—before she was to go away to college.

"I don't want to leave Rolynka," Vicky had said, her arms wrapped around her skinny legs as she watched the needles fly in her mother's hands and the strands of wool take shape.
