Here is a super, simple card that is also economical for mailing (meaning you won't have to pay more postage because of "lumps"). The inspiration for this card comes from Nicole Heady.
The ornament dots on the Christmas tree are just dots punched out of scarlet cardstock and glued on. The edge of the white paper I distressed with an edge distressor. Instead of using ribbon, I used a striped stamp to add some visual interest and break up the snowflakes.
