Like rooibos tea or steamed milk before bed, a hot water bottle quickly becomes a ritual. Jennifer Evans designed this pretty, practical cozy that knits up in a trice. Fill your cheerful red rubber bottle with very hot tap water, tuck it between your sheets and turn the thermostat down. No more cold toes! And wouldn't it make a thoughtful gift? Finished size: Approx. 17" / 43cm around x 11" / 28cm long to base of neck; to fit a standard hot water bottle.
