There's still a long way to go, but I'm beginning to get a feel for it. Up close it's still pretty messy, so I'm thinking maybe I should get a loupe - a cheap, weak-ish one should do it. (Don't tell me it's time for bifocals already - I'm not that old!)
I'm not sure about this Liquitex brush-on varnish either. The paint (mainly Liquitex Ink!) seems to be staining through it, at least faintly. It's ok for practice, but I'll have to find a better solution before I start on the real projects. That most likely means MSC and a respirator, and I'd like to keep it simple and non-intimidating for now.
