Hubby and I do stockings for each other. Not sure what I'll put in this year's yet, but we always have some nice chocolates (Thorntons usually), a toblerone, chocolate orange and chocolate coins. Last year I got him a packet of posh tea bags and a 'ring for tea' bell from Next. I have put CDs, books, PJ trousers and aftershave in there before. You could also put in socks, underwear, any toiletries he would use, alcohol miniatures. Does he have any hobbies? Is there anything related to them you could put in?
