I think that's a pretty big key to it! I tried the "paint wash" method, and it is definitely something I'd need to practice a lot to get any good at. Brush painting is quite a bit different that airbrush painting!
Part of the idea behind the post in the first place is the idea of being highly mobile. I've been reading about families who "roadschool," in which they travel around the country in an RV, converted school bus, or camper. Generally this is a couple year journey, and they get to take their kids all over the country and see all sorts of things, emphasis put on first hand experiences instead of textbook knowledge. One dynamic of this includes limited storage space... I would't be able to bring my whole shop, so I've been "what if-ing" my way through the process, what tools would I bring, what type of lures would I make, would I just take a break (probably not!), how would I simplify the whole process as much as possible.
One bonus of this idea is my kids and I could catch fish in all 48 continental states and maybe some provinces in Canada too! Oh the possibilities...
