We're loving all of the cross-holiday ideas here on pinterest, like this one --> "Menorah Tree" Christmas/Hannukah Interchangeable Card
Great idea at the beginning of the aisle. Guests can write words of wisdom before taking their seat!
As guests arrive, they leave sweet notes with well wishes for the bride and groom on the "Wishing Tree" made from tree branches placed in a vase of bird seed. In addition, guests fill in their names and addresses on blank envelopes, making it super easy for the bride and groom to send out thank you cards (saves lots of time on having to look up addresses & address envelopes)...great idea!!
