Pop-up cards are a fun and creative way to make your Christmas cards stand out. To make a pop-up card, you'll need some supplies including: scissors, cardstock, a pencil, paper clips, and glue. First, you'll need to choose a design for your pop-up card. It could be a snowman, a reindeer, or any other festive character. Once you've chosen your design, you'll need to trace it onto a piece of cardstock. Next, you'll need to cut out the design and fold it so that it pops out when the card is opened.
