Unique Ways to Give Christmas Cards?

Last year I knew I had alot of extra Christmas cards so I mailed each with a note wishing a Very Merry Christmas an New Year an also a thank you for making our country so proud an helping to keep us safe to our military bases overseas. I had the address from the ones that I send coupons to all year around. From the letters that I recieved back I knew this was something that was very much appriciated.
