The first main difference between a commission project and a prototype is the choice of wood. My base woods are always maple and walnut. I love the contrast and they are relatively clean and stable. I thought the truck needed some detail to break up the solid side so I added the pin striping. I liked how it came out so I did the same on the pick up truck. I also added fuel tanks on the cab. It is a little bit of detail that added a lot. The sedan had to be dark so walnut was the obvious choice for that car. The sports car had to be two toned; black and red. It was made out of cherry and walnut. The beetle needed character. The standard wood tones would not have worked so I purchased purple heart. Yes it is purple with no stain. I was going back and forth between purple and yellow hear and I remember how much of a pain it is to work with the material.
I take the commission jobs seriously and try to add my little touches to it. The drawings will not call out the pin striping or the wood species. I also like to have contrasting woods. I would expect that people who use my plans would make the project their own. I have learned that most plans are general guidelines that can have a personal touch added.
