Knitters call it the sweater curse: knit a sweater for a significant other and they'll break up with you — in one version, before the sweater is even finished. In a 2005 poll, 15% of active knitters said they'd experienced the curse firsthand, and another 41% considered it a possibility to be taken seriously.
Knitting literature treats it as a real-world pitfall with rational explanations rather than a supernatural force. A hand-knit sweater is an enormous investment — sometimes over $100 in yarn, around 100,000 stitches, and up to a year of work — so one theory is simple timing: knitting takes long enough that plenty of relationships would have ended on their own before the sweater was finished. Another is that such an intimate and domestic gift forces the recipient to evaluate the relationship, and some end it before the sweater becomes an obligation. Or the recipient just doesn't want to wear anything hand-knit.
The standard advice for avoiding the curse: start small with hats, mittens, or socks, involve the partner in choosing the design and colors, and follow their suggestions even when you disagree. Many knitters simply wait until marriage before starting a sweater.
