As a follow-up, this is my simple setup for watercolor using 6x6 or 5x7 Ampersand aquabord panels.
Again, I used double-side tape to secure the panel to the larger sheet of watercolor paper beneath it. That supporting sheet allows me to test colors and lines before applying them to the panel. (There are no changes allowed with one of these aquabords – it’s a highwire act with no second chances!)
I should note that the image on my iPad is a photo I took on my honeymoon last October. The pic was practically monochrome in the original but came to life with color replacement and curves tweaks in PS. And I added a second layer on which I drew a grid dividing it 4 ways on each side… corresponding to the marks on the support paper. (As far as I can tell, the only way to print a grid in PS without a 3rd party tool is by drawing it yourself with the pencil or brush tool.)
