I spent the afternoon sketching outside on my back porch.
And my ACEO cards are done and living in their clear sleeves and inserted into Strathmore Frame Cards. I finished all of them yesterday. I activated the Derwent Inktense pencils with a brush I acquired in the UK at the art supply store in Bath, on the recommendation of the saleswoman. It's a Pentel Aquash brush, with a self-contained water reservoir - rather designed specifically to use with watercolor pencils, I think. It lets you work in watercolor out in the wild without having to deal with bowls of water.
Here are photos of some of the cards before cutting and packaging:
