Decorate for both holidays. Find or make Hanukkah-themed decorations for your Christmas tree. Wrap gifts in both Hanukkah and Christmas wrapping paper. Place holly sprigs around the Menorah. Be as creative as you like with this. If there are children in your household invite them to make suggestions.
Prepare food from both traditions. For example, make cut-out sugar cookies in Hanukkah shapes. Decorate them with colored sugar in red and green for Christmas and blue and yellow for Hanukkah. At your holiday meal serve dishes traditional to both your Christian and Jewish familymembers.
Combine gift-giving traditions. Allow children to select one gift from under the tree for each of the eight nights of Hanukkah.
When you light the Menorah each night, sing both a Christmas song and the traditional Hebrew chant.
Hold a latke party for Christmas Eve. Have children and adults participate in making the traditional potato pancakes. Serve with the potato pancakes with homemade apple sauce and eat them around the Christmas tree.
Make dreidels available for children's games on Christmas Eve. Or combine Christmas carol singing with the dreidel game by having a song for every round of the game.
