There is an abundance of information about traditional gifts for each anniversary. Some are gold, silver, diamonds, crystal, etc. Some are extremely romantic. Some are practical.

We have already successfully passed all the paper, cardboard, tinfoil, and etched glass marriage markers (they are not all cool jewelry mileposts - ha).
This is what is said about number 17.
