Christmas card

A Christmas card is a special type of card that people send to their friends and family during the holiday season. It's a way of telling them that you are thinking of them and wishing them a happy holiday.

Imagine you drew a really pretty picture and wanted to give it to your mom or dad to show them that you love them. A Christmas card is kind of like that, but instead of a picture, it usually has a special message or design on it.

Sometimes people make their own Christmas cards by using colorful paper, stickers, or even by drawing a picture themselves. Other times, people buy Christmas cards that are already made and have messages and pictures printed on them.

When you send a Christmas card, you usually put it in a special envelope with your friend or family member's name and address on it, and then you put a stamp on it so that the mailman can deliver it to them.

Receiving a Christmas card can be really special and make people feel happy and loved during the holiday season.
