Short story or Novella published in a collection which I read in the 1970s. Paralyzed woman secretly rolls and twists the fringe on her lap blanket with her fingers. Spoiler.

[Laura]

Protagonist is terrified of "yellow starfish hands." She has a nurse who switched from knitting to tatting lace when she noticed the woman's fixation on her knitting needles. (view spoiler)[

She became paralyzed from falling down the stairs after discovering the hanged body of her son, an apparent suicide. (hide spoiler)]

Actually, I may have read this in the 80s...

Laura, what's the genre or mood - e.g., for adults or teens? mystery, suspense, horror?
