Should I be confining the mixes to small concentrated areas to avoid increase surface area so they're not constantly drying out? Or are people adding gum arabic to avoid this?
Hi roxicus, with gouache, I find when you are mixing colours, keep your colour mixes in a gloop rather than spreading them out. They will dry out far quicker if spread thinly. Use a palette knife for large mixtures, which when you do, is fine to have it spread out to get a good mix going but once you attain your colour, scoop it up in one go and lay it out. You do this by turning the knife upside down and laying it on one edge, and proceed to flatten the knife to the other edge, this squeezes the paint out into a gloop.
One more tip, wet a kitchen towel, squeeze it until it doesn't drip water(have it damp) and place your finished mixtures on this.
