It’s hard to find something worthy of the greatest woman you know, but these Christmas gifts for Grandma are pretty special. Give her a hug, even from afar, with a silk or cashmere scarf. Make her smile every morning with an artwork that includes each member of the family. Or give her a well-earned rest with a hamper of fragrant teas (or a bottle of artisan gin). The age-old question of 'what to get Grandma for Christmas' is about to be answered.
