For travelling I am taking half a dozen full sheets of watercolour paper to use with acrylics instead of canvases in order to save room.  I remembered that I was supposed to coat the paper with Gesso, and so I used some black and some white, and in some areas the two made a nice grey.  I have divided the sheet into eighths with green Frog Tape, and am all set to go on my first eight paintings.
