We did the maracas as well!! I love when I go to friend's houses and see the maracas lying on a bookshelf or somewhere in their house! Such a great memory!
We did maracas as our wedding favors and they were a HUGE hit! We had one placed at every table setting and I tied a note on each of them (the size of a business card) and on one side it said:
"Instead of tapping on your glass, Heres a system with Mexican class. Stand and shake with all your might, To see the groom kiss his bride tonight."
Then on the other side we wrote a short Thank You note to our guests.
The maracas were ordered from Amols and were SUCH a great price!
