anniversary gifts

any good ideas on gifts for my friends anniversary??? there are so many things i owuld buy for my friend but i feel like i should buy a gift for her and her husband... i don't have any ideas!!!!!!

How many years have they been married?? I know the 1st year is paper goods. Every year there is a theme. I am sure you can find them on the Internet. I just know what the first year is because my friend just celebrated her first anniversary.

second is cotton (traditional) and china (modern)

thanks!
