For my midway card, I have used an image from Sparkle n Sprinkle called Holiday Cheer Set and papers from Décosse's Dynamite Doodles.
The inside of the card has a box for adding treats to:
I also used some acetate which I embossed for the window of the box. The word "Christmas" is a sticker. I added a pink bow and some silver snowflake ribbon.
I followed a tutorial from Beccy's Place for the basic card shape.
