You might not have enough time for this, but I'm doing holiday crackers for my Christmas Eve guests. I've been saving toilet paper rolls all year, and I cover them with tissue paper, use a gold or silver paint pen to write their names on them, sprinkle them with glitter and fill them with candy kisses and peppermints. You could make them and put them in a crystal or wooden bowl by the door for them to pick up on their way out...use curling ribbon and they look so festive and pretty! You wouldn't even have to put names on them...just a Christmas sticker or cutout.
Another idea might be to make salt dough ornaments for each couple. I like to make these in a snowflake shape, paint them white and sprinkle them with clear glitter while the paint is still wet. If you make a hole in the top with a straw before you bake it, you could use a gold or silver (or any other color) ribbon to hang them with. They really are quite elegant and festive.
