This was so much fun! (Will it sell is another question). As a former potter, I loved the texture, colors and watching the colors change as it dried. With forethought, I created a color board so I would know what I used, and photographed the stages. Buy lots of white if you’re working on boards, and seal your colors in tight containers. To get started and “paint” (2) 24x24, (2) 12x12, wood boards all up and all in cost about $200, but I have guitar a lot left if it doesn’t dry out too soon.
