I have been using the Mosaic embossing folder for the back ground on a lot of my Christmas Cards.  I like the way it kind of resembles a Christmas ornament.  This set is called Wishing you and can be found in the Holiday catalog on page 23.  This set can be used for birthdays too just by changing the color of the presents and the sentiment.  Actually, if you emboss them with silver or gold you can use them for Weddings and Anniversaries also.  You can get a lot of mileage from this one set.
