This could take the form of one of the other winter holidays (Hanukkah, Kwanzaa, New Year or Winter Solstice to name a few); or you could go totally non-denominational with a general winter-themed design.
I decided to go with a snowflake-themed design because I find them so peaceful. I've had this glimmer sprayed die-cut embossed snowflake on my studio table for months that was left over from a failed project ... it finally found a home. This angle shows a bit of the glimmer.
I used this week's Cardabilities sketch which combined the snowflake with a black doily and some Stampin' Up felt snowflakes.
I used a blue shimmery cardstock for the border & flourishes and finished with silver sequins.
