We spent a fair chunk of Labor Day weekend lazily stretched out on picnic blankets, engaged in imaginative cloud gazing with our son. There's a hedgehog, a Lego guy, a banana. But yesterday we were in the mood for some more, and not a single patch of condensed water vapor to be seen. So we did the next best thing - we fashioned our own to hang indoors. They took literally minutes to put together, and the effect was surprisingly transporting.
