I'm on the decorating committee for the middle school orchestra. This, of course, means I have zero budget to decorate for the winter concert. I remembered that my daughter made these cool 3D snowflakes last year in art class, so I decided to whip up a dozen with the other committee members to jazz up the stage.
Here's a great video tutorial on how to make these. They are super easy, but they take some time since there's a lot of folding and cutting. Use the biggest paper you can find (I used 11 x 17).
