I want to bring my urban sketching tools with me whenever I go out, so that I'll have them even for impromptu painting. I made a card that will easily fit my A6 sketchbook and attached Peerless transparent watercolors using rubber adhesive, and secured sheets of paper palette with staples and washi tape.
I also bought a tiny tin can for my watercolor half pans (Van Gogh Watercolor Pans in Prussian Blue, Permanent Red, Yellow Ochre, and Viridian; and Rembrandt Watercolor Pan in Burnt Sienna). I can now bring a portable studio inside my small sling bag. :)
I want to practice freehand urban watercolor sketching on an affordable sketchbook that I wouldn't mind messing around with. However, a Monologue A6 soft sketchbook is too precious because it's almost always sold out here, and a Moleskine watercolour pocket notebook is too expensive.
Since a dirt-cheap pocket watercolor sketchbook is not readily available, I decided to make my own. I bought a Canson watercolor paper pack with 10 sheets, which I cut into four pieces each. Then, I used a puncher and a spiral wire from an old sketchpad to bind them. I was able to make a 40-sheet pocket sketchpad, and even though it's still a crude version, it will do for now. :)
