So I need to break up the lozenge into 6 sections then re-lay them then?
USRanger,
Just as a warning: This issue is far, far more complex than this.

Fokker D.VII was manufactured by three main firms (Fokker, Albatross Werke, Ostdeutsche Albatross Werke) and each of them used their own unique covering practices/stencils and so on...over which, the pilots applied their own personal markings in the units. There also were different types of lozenge fabric, with different shades, patterns and...so on.

AFAIK Bolle's plane is a Fokker built, since the F-designation. Only the Fokker built machines with BMW-engines got the F-designation. Other manufacturers fitted BMW engines into their machines aswell but there wasn't any distinction as far as the designation goes.
I'll send you a package regarding this stuff in a PM.
Should I be using the default as a reference for skinning purposes?
Generally speaking, I'd say that's a no.

I would generally suggest starting by doing a blank template and starting from there with an open mind.
Btw, check the top projection of that Bolle's aircraft in that osprey book (page 45) and you can see the seams of the lozenge strips.
...I'm going to do this as historically accurate as possible for an amateur like myself. Looks like I got some lozenge work to do.
You have the right attitude.

Having an open mind and doing a lot of research goes a long way!
