The cards are 4" square and I used a base of Early Espresso, a Very Vanilla mat and the Mocha Morning Specialty DSP.
The images are from Welcome Christmas Stamp Set and little 'Merry Christmas' from the Petite Pairs Stamp Set. They were stamped in Versamark and then heat embossed with Gold Embossing Powder.
I also made a pizza box to store the cards in. The top of the box has the same mat and Mocha Morning DSP. I created a belly band out of Very Vanilla and added the image to the top section.
