The Festival of Trees stamp set with coordinating punch is super quick and easy to use for Christmas cards. Like this one.
I started with a Whisper White card and stamped the sentiment in Bermuda Bay ink before embossing the card front with the big polka dots. The tree was stamped in Pool Party, then the dots stamped over it in Bermuda Bay. A silver foil star with a bow of twine finishes the card. I CASE'd most everything except the tree color from http://jillsink.com.
