This is a lot of fun if you have small children. Get a pile of cardstock in different colors, and some white paper and scissors. Fold the white paper into eighths, and have your kids cut out snowflakes. Then glue the white snowflakes onto the front of the cardstock. Use your paint marker or calligraphy pen to write a Yule greeting on the inside.
Silly Sun Cards
Cut out circles of yellow construction paper, and thin strips in yellow and orange. Paste a circle in the center of the front of a card, with the strips radiating out from behind it like the rays of the sun. Once the glue has dried, have your kids draw funny faces on the suns. Write a greeting on the inside of the card.
