Save the date ideas?

Does anyone have any save the date ideas besides a card or magnet? Some creative ones I've heard are:
- STD fans
- STD cookie
- a poker chip

etc

TIA

edit;
My colors are red and gold, no theme as of yet. it may be ballroom dancing cause thats how FH and I met.

we did postcards using pictures from our e-shoot. still getting compliments weeks later after they went out. zazzle.com
