We were supposed to be learning about painting misty rivers.  I have an ample supply of my own photos of those for reference, so I dug out a number of them, and put them on an old minilaptop that is ideal for this purpose, since it doesn't have enough disk space to apply Windows updates and therefore isn't really safe to connect to the internet, but is fine for browsing photos off a USB stick. Which is just what I need in the art class church hall, which has no wifi, and barely even a mobile signal.   But I forgot that the dratted thing won't start unless the battery is charged, so instead this is adapted from a photo of Glastonbury Tor that someone had clipped out of a newspaper.  With some added water.
