One of our Christmas projects on the go this year is to experiment with making window stars. I have seen many of them around in past years at friends homes, and have been dying to try them. William helped out with folding the larger stars, but the smaller one was a little too finicky for his six-year-old fingers. These ones are on the kitchen window right above the sink, and I love the way they look in the morning sun. Believe it or not, they actually make washing the dishes somewhat enjoyable!
We were able to get the kite paper at our local Waldorf school, and got the tutorials off of the Internet. These ones are really about as simple as you can get, but there are patterns out there for more complex and even more beautiful stars.
Here are a few links to get you started:
This one is a great place to start
