One of the easiest ways to made a big difference in your cards is embossing folders. Takes no time at all to run a piece of CS through the folder and it can look so awesome.
The folder used is Northern Flurry #120902 pg 189 in the main catty.
Image is from Embellished Events #126497(clear) pg 40
I love this stamp set as it gives you 6 different images for so many events, plus the sentiments, in this case the Merry Christmas, is separate from the image stamp so you can mix and match them.
