I got a Guerilla Painter pochade box for Christmas, and 8 months later, I finally got around to using it aside from playing around inside the house or in the back yard. This is a very different experience.
Among my challenges:
The palette is smaller than I am used to
The light is very different from my studio
No good place to keep my brush washer (I wound up sticking it on the picnic table)
Not sure how I feel about the palette and panel being so close to each other.
