Came across this good idea proposed seven years ago by Via Malaga.
The benefits of the Palette Garage are:
keeping your paints fluid and open using clove oil in a sealed and transparent housing.
attaching securely to a pochade, avoiding cumulative build up in the pochade.
made of cheap and easily available materials.
this version uses Velcro dots, however later she uses blue tack or two locating pins.
better paint management, less waste and less clean up.https://youtu.be/klsLlnnOlPc
