You can fill empty toilet paper rolls with small candy and tiny toys for a party favor. Once you fill it up close up each end and decorate the tube, or wrap in tissue paper and tie ends up with a pretty ribbon.
You will need a length of butcher paper the length of your table. Spread the butcher paper out on table and decorate using crayons, markers, etc. This makes a very cute tablecloth that doubles as a memory!
Make a family love book by asking each member of your family to draw a picture of something or someone they love. Let the children dictate a sentence about their drawing and print on the page. Your children can also attach the family valentines to pages. Older children can write a short story about something your family did for Valentine's Day. Attach together for a wonderful memory "family love book". Be sure to date it!
Here's an idea for your next overnight party. Make sure you have a pre-washed T-shirt for each kid. (they could bring them from home or you could supply them). Using fabric paints and markers each kid can design their T-shirt on the front. Get everyone to sign everybody else's T-shirt. You can even date them. Let them dry overnight and everyone has a one of a kind party favor! This idea is not limited to T-shirts, try decorating hot chocolate mugs, or bookmarks with these ideas in mind.
