The system mounts on a standard photo tripod with a 1/4” bolt. Magnets are countersunk into the adjustable hinged palette holder, allowing for the metal watercolor palette (I put together a custom watercolor set filling 1/2 pans with selected colors and a metal palette) or the homemade metal palette pictured in the middle photo (a painted metal pencil box) to adhere.
Magnets are also glued to the bottom of the water containers, allowing them to hold fast to the metal palette or hinged lower section (you can see how they are sticking to the lower section in the top photo and to the palette in the middle photo). The clamps hold the sketchbook in place. Fun!
