To hang your Christmas cards, you can use either tape or push pins. If you're using tape, simply place a piece of tape on the back of each card and then press it against the wall or other surface. For push pins, you can push the pin into the wall and then attach the card to it. Alternatively, you can use thumbtacks, string, or command hooks to hang your cards. Remember to choose a spot that is out of the way of foot traffic and not too high or low on the wall so the cards are easy to see and reach. Happy hanging!
