A small sketch book, mechanical pencil, and eraser. These are essential travelling or out-and-about companions for any botanical artist.
You know what’s going to happen on that one occasion that you don’t have them handy—you’ll come across that unusual flower, interesting leaf, or never-before-seen mushroom. Not being able to record a find can be the height of frustration.
With a small sketch book, mechanical pencil, and eraser you can sketch the subject, make observational notes, note it’s location and then return to your studio to identify and name it. Who knows? It could be the beginning of great painting.
