This tutorial shows how to make a floating Chinese lantern. I like this tutorial because it has fine black line drawings and technical drawings of specific measurements. This is useful when it comes to building something that needs to be symmetrical on both sides.

I love these Chinese lanterns, especially when they fill the sky and float away! This tutorial looks very straight forward, but the photos could be much better and clearer.
