Re: Watercolor sketching kits - survey and ideas
Brian: Gee, I don't really have a tiny sketch set up... although in my stash are maybe enough bits to build one. One thing I have is a little W&N travel brush kit, (the brushes with covers you swap around as the handle). I mention this because one is a flat about 3/8" wide. I'd always wondered why they were not made but it turns out they are, (or were); Difficult to close-up without catching hairs unless very carefully handled. I suspect a cut-down 1/2" flat would work better with less cost.
have fun, Dave
