I've been playing around with gouache a bit lately. To study, I've been watching Jeff Watts videos and practicing small heads to get a feel for the paint and trying to get control of my values. I've got a long way to go, but I can tell gouache is the medium for me. I like that it can be used in an opaque manner, and that I can set it aside and work on it whenever I have time. Even the drying time just seems to suit my temperament. I'm sure I'll do larger studies, color studies, etc. For the short term, I just want to create a painting habit in my life to build up brush mileage as Jeff Watts says. I'll post to this thread as I go to track progress.
