Kite!

We got kites ages ago and finally got around to painting and flying them! It did keep turning upside down, but that might just be my kite-flying ability. We had a lot of fun in any case, and I could always add a tail if necessary (maybe a salmon?).

The kites were Asobi Ecoflyers, which are made from bamboo and silk, and are very cheap as well as being eco-friendly! I would forget the felt-tips they come with though. I painted mine with thin washes of dilute acylic paint.
