I've had the majority of these paints hanging on my pegboard for over a year languishing because I don't feel well enough acquainted with them - this was the kick in the butt I needed to start learning their characteristics and personalities!  Regular gouache up top - mix of Holbein and W&N; acrylic gouach (all Holbein) down below.  Always excited when Jen posts a new class and this one didn't disappoint - still need holes punched in all but these are so much more useful than color charts!  Looking forward to expanding into some of my other media here. . .
