This year I gave family members - fruit cake for those who enjoy it with alternative for those who don't, a joint family rechargeable spotlight that can flash when walking in the dark ( I love mine so got another for myself when they were 75% off for Black Friday), some socks and an alpaca scarf each which is wonderfully soft and warm. Simple and easy to mail.
Keeping it simple works well.
While I appreciate thoughtfulness, the pressure to respond to an unwanted gift at Christmas time is a pain.
