Most people like to celebrate wedding anniversaries with presents and perhaps have an evening out at a favorite restaurant or theater.
Traditionally, certain materials are associated with individual years in the course of a marriage, the idea being that anniversary presents in those years should be made out of those particular materials. So, if you want to uphold the custom - flowers and boxes of chocolates notwithstanding - the list below gives the materials generally associated with each year. They do vary slightly, however; paper is sometimes given for the first year, leather for the twelfth, ivory for the fourteenth, wool for the fortieth, and silk for the forty-fifth.
First Cotton or Paper
Fourth Silk or Flowers
Seventh Wool or Copper
Twelfth Silk and Fine Linen or Leather
