Take their wedding invitation, cut into strips and placed in a glass ball. Give to newlywed couple for their first Christmas. Would work for baby showers and other things too. Such a good idea, especially now that I know tons of people getting married.
It'd be cute to take the bottom of each year's tree, put the date on it, and make it an ornament the following years! Would like to make one for each year we have been together and then add charms hanging off for important events....wedding, births, houses, etc.
