I'm not changing it this year - we have too much going on right now. (We're moving house the week of Christmas!) But last year, I recolored my template images to Christmassey colors and I added a Santa hat to the cartoon me in the header image, and added a silhouette of a Christmas tree to the silhouettes of my kids. It came out pretty cute, I thought. Still looked the same as every, except festive for Christmas!
