Handmade ornaments are such an easy thing to do. Have you looked at all the tutorials out there? Just about anything you could want to do is available. How about this 3D Paper Snowflake?
Last year my family did the 12 Days of Christmas for my parents. (Had to get it in before babies 13 and 14 showed up this year.) Since my kids are the oldest, we did the first few. Larissa had done a partridge and a pear in one of her posts. These were such a cute idea, I got the kids working on a set.
They had such a good time! My oldest (who has the attention span of a fish) almost made her ornament in one sitting.
Make the ornament sentimental. My husband's aunt made snowmen for all the grandkids out of his grandmother's chenille bedspread.
