Here is my card:
I used Christmas Mail Susie set which is available here and coloured her with my Copics. The Post Box and sentiment come with the set. I added some Star Dust Stickles and Glamour Dust to them. The papers are Christmas Birds by Gina Jane. The card shape was made using my Go Kreate XXL Square Frilly Frames. I used Spellbinders Classic Circles, Tear Drop Circles and Beaded Oval dies and Dienamics Pierced Oval Stax die.
